Fly Fishing Tech Tips: Sonar Leaders Vs PolyLeaders 

Your approach and attention to the minutiae of the function behind these products is hugely appreciated!

Very interesting video! Cheeky Airflo, they make faster sinking polyleaders by adding a thicker coating instead of increasing its density! They should at least print the grain weights on the packagings. Recently I have been using OPST level sink tips, could not be happier with their selections although I wish that they have levelled poly leaders. IMHO (sorry Charles!) turning over a 10 feet light weight poly leader is a function of casting efficiency and matching of tackle rather than a topic of tapered vs non tapered coating.

Great video! Thanks for going as in depth as you did! I'm impressed with the Scientific Anglers Spey lite integrated! Going to pick up some of the sonar leaders today for the extended weekend.

Thanks for this. It confirms my experience exactly though I've been using Airflo and the old Rio Versileader kit. Sadly, Rio doesn't distribute the whole Versileader kit any more. It was all the same grain weight 10 ft. tapered leaders; perfect for Scandi use. You can buy them as individuals but not as wide a range. Like you, I found the heavier Airflo polyleaders good for Skagit only.

Hi Peter...thanks for the comparison, very interesting video. I recently purchased a IMX Pro 41111 and use a 330gr skagit scout which has been very good. If I waned to try a Scandi head would an SA Scandi 270 grain be a good choice or do you prefer the Rage head? Thanks for all the videos!

Hi Peter! Sorry for an offtopic question, that's been hunting me for a long time. How would you handle a leader building without an access to a fly shop to buy spools of lines with known stiffnesses? I have only a choice of buying generic brands of lines in asortment of various diameters/pound tests and unknown stiffness of each. How would you match them together? To build say 7.5ft leader for a 4 weight fly line? I fish wet flies mostly.Hook size is 14. Thanks a lot and please keep up your good work! Best regards, Alex

What can I say? The more I know, the less I understand! Two-handed rods are not that common here so I depend on you for advice! We're used to floating lines and plain tapered leaders. I'm going from forty years of single-handed fishing to trying to learn how to be effective with an 11' switch rod. I got a Rage head because you liked them (450 grain for my #7 rod, right in the middle of its recommended grain weight). The fly shop sold me a 14' floating Polyleader and a 10' slow sink to go with it. Why the difference in length? Who am I to question them.. Then last week a couple of fellows with connections to Sweden came floating down the river with 16' rods. They seemed to know what they were doing and scoffed at any Polyleaders. They weren't crazy about the Rage heads either. Not Scandi enough for them I suppose. And since I'm targeting Atlantic salmon, they thought the heads should be lighter than the steelhead recommendation. I can see where a lot of trial and error can become expensive, time-consuming, and even more frustrating. I'm appreciating my Wullf Ambush line on my single-handed rod more and more... Once again, thanks for all your videos!

Would you better take the 10ft or the 7ft leaders for a normal single handed 9ft rod? For what are the 10ft vs. the 7ft? Sorry if this is a silly question I am just fishing with fly for two years and the whole line stuff makes me really insecure still!

please explain how SA gets different sink rates with same density line??

Can you show their action inside swimming pool?🤔

Did you measure the length of them?

The most beautiful of this video is the LYMAN powder scale ….. I don’t share the opinions on this video , in spite I really like this channel and Peter Charles explanations, but not this time. Sorry
