I read this post a few months ago and have had "The Push" queued in my Youtube feed since. I finally got around to watching it this weekend.
This is, hands down, the best traditional archery video I have ever seen. GREAT work.
Prior to watching it, I had no interest in tinkering with my shooting style. I'm happy with my skill level. Still, I played with the fixed crawl this weekend and think it has some real merit. It will take some time to get used to, but I can see myself becoming a fixed crawl shooter....
If you haven't yet watched it, do it. Now.
