I'm going to be honest. I just ride a bike, which means that some of your recent videos aren't central to my interests. But I also know that you upload some of the best motorcycle videos on RU-vid, so I'm going to watch them anyway :) Hey, I might learn a few things.
Cheers mate, I really appreciate you taking the time to add that comment. Sometimes it feels like I am dropping videos into a RU-vid black hole....!!! 👍
Fill that sumbitch as much as you can. When I did a couple of classes with “professional” guys I was surprised how full the bags were. When I came home from the first class I filled mine up more. I use dried sand and pack it in hard. Depending on the bag you might be able to add or remove shot to suit. One of my bags has a Velcro closure but the other is riveted shut which is more of a pain to adjust.
