Olsen’s Improved Blowtorch nymph: fly tying tutorial 

Great fly and great tie. I love the attention you give to technique in your videos, it really helps me focus on the small things. Every wrap counts if you want to tie thin nymphs. Thank you.

Keep up the great work. As a beginner I have watched and tied along with a lot of videos, but I have to say your instructions and explanations are some of the best. Knowing the reasons behind doing something is much more important than just imitating someone else tying.

Great tutorial, loved the tips on keeping the fly slim

I really enjoy watching you tie. All of your ties are very helpful. Thanks

It’s kind of crazy but you verbalized everything I’ve been thinking about watching a lot of these videos. Of course I’m still learning and I’ve been doing this a while but watching people ignore simple technique gets frustrating so I appreciate everything you said here. Thanks again

Finally someone sets the record straight ! 🙏 I watch a lot your vids and they are the real deal. I studied euro in spain and Lance Egan is my co-host on my podcast. You’re a legend man, great teacher. I’m a big fan 🤜🤛

Good tips, thoughtful commentaries. Nice work!! I am subscribing. 👍

Another great video …. Meticulous attention to detail . Thanks so much for the technique instruction.

Brilliant, well done, think your tying philosophy is great!

Great video!! I tie them the other way. I’m gonna give this one a try. Thank for sharing!

Outstanding

Great video. Thanks for posting it. I used to tie in CDC by its rachis, but I didn't like the bulk it added. So now I split 18/0 GSP thread and just use the CDC barbs. This *does* look quite like Olsen's Crossover Nymph, as you pointed out to me before. I'll tie some of these up for my annual trip to MT. Luckily I have all the ingredients you listed in your note.

Thanks for the talk about technique. Very helpful to me, at least.

Fantastic detail. I’ve been using midge braid to get the body thinner than I can get it with dubbing

Thin to win! I'm new to perdigons and I'm guilty of wrapping back and forth to tie in materials. The tip to flatten the thread and make 3 wraps to the front to tie in the wire is a good one. I would have wound all the way up tied it in and wrapped all the way back. Your thread control is terrific. The average tier has no idea about flatting and sharpening the thread. Keep making videos, I enjoy the good ones, unfortunally there are many out there like you said that are using poor thread and material control. Pinching the cdc makes it look more natural than trimming them with scissors.

Nice clean tie ODTB! When u mentioned "other tiers" not doing it correctly I thought, "he's probably talking about my old videos" haha. Im still learning but I appreciate your precision to tying. So similar to Egans Red Dart but with an orange tag. I just tied sum of these as I recapped your video. Thank you for sharing and Tight lines "New sub"..👌

As always great tutorial.if I can add one aspect for those wanting to beginning fly tying: pick 4 main recipes, otherwise you can go down the rabbit hole chasing all the required materials.

Hey man. You have great videos but it’s also great you give credit where credit is due! Keep up the great videos!

Great instruction on this tie..one thing I noticed that you do ..which another Tier explains on another channel ..is you twist your dubbing on your thread clockwise..I notice other tiers twist it on counter clockwise and when they go to wrap it on the hook it always blows out and they find themselves always adjusting their dubbing. If your a right handed tier your thread wants to naturally cord up which would be a clockwise rotation further more tightening your dubbing. Curious on your thoughts.

Thank you Corey for your attention to detail. Would you please suggest a book for beginners fly tying? Appreciate your help

Excellent video as always. One question. Why do you choose to use the stem technique to get the CDC on for this fly but prefer a split thread technique for others? Thank you

Thanks for the hints and measurements good stuff . Do you add lead to this

I just watched this again Cory. Nice job!. I was wondering what size hooks you tie and what matching beads on this pattern. I just tied up some Walts, Quilldigons and some olive Krystal flash perdigons. I am waiting for the mailman to bring my black Gulff for the wingcases

Great job Corey, you always stress what is really important. What are your thoughts about adding the cdc with a clip and dubbing loop rather than using the stem? I would think you might be able to keep the head thinner that way.. Thanks again

I do think you need to build a ramp of sorts with countersunk beads. They tend to have a lot more wiggle than slotted beads, especially when you're at the upper limit of a bead size for a particular size hook, much less oversizing a bead (even by one size). Another reason to go with slotted beads, I guess. Also -- any reason to tie the CDC in with the quill on some flies and do it with a dubbing loop on others? Are the techniques interchangeable in your mind? Thanks again ODTB.

Hey Cory, I'm really trying to learn the why, not just the how. What determines whether you use the quill vs a dubbing loop? I know you usually use a loop.

I think the trout where I fish don’t like them!Lol. I tie one on every trip or so and they won’t take! I can put on a second fly too... Newberg hare’s w/ pink bead, Walt’s worm, Sexy Walts, soft hackle bead head and they take. I’ll keep trying!Best, Tony

Thanks for sharing. So the video where he uses some lead wire is not the most current?

Again, great video and thanks for the reply. I’m guessing with the heavy bead, you fish this as a point fly, true??

Hi Corey, I usually use a dubbing loop for ice dub, and noticed that you wrap it straight to the thread, does that give you a tighter noodle ? Thanks much

Is this a copper color bead? Also it looks like you used UV pink ice dub but said UV shrimp pink. Which is best?

Did I miss hook and bead size? Would you put some wire wraps on this?

Have you tried this pattern with fl green tag and fl green collar?

What brand of glue was that?

instead of ice dub.I use midge diamond braid in peacock.It's much thinner.

Dark grey khaki? That's a new one.

It would be helpful if you told us what size hook and bead you are using, both in the video and in the description down below. Otherwise a good video. Thanks

Nah that's the blow dart🤘🏻

What CDC do you use?

What size hook/ bead do you usually tie this pattern?

👍👌👏👏👏👏👏👍👍👌👌

Why don’t you split the thread and add the cdc that way. You’ll get two flies out of one feather that way

I've moved from Hareline ice dub to slf prism dubbing...so much easier to dub

Kind of an orange dart

Stripping half the CDC quill and tying it in is so wasteful. The dubbing loop method for CDC hackle is less wasteful and more effective.
