Another concern is that beginning archers may not understand that just any bow won't work this way at maximum efficiency, no matter how good the technique is for improving aim.
This is definitely worth noting. Matt does a good job explaining most of the technique in The Push, but I don't recall if he touched on this. String walking is primarily a target system, where most bows are ILF. I also wonder how tune is effected going from a 40 yard crawl to a 15 yard crawl.
As for beginning archers & converts playing with it, most don't have the form or experience tuning to achieve anything near maximum efficiency as it is. If using an aiming system helps to nail down form & tune quicker, I'd say it's a good trade off.
When I converted I spent the first 6 months or so gap shooting with a recurve, though I didn't know there was a name for it, with pretty good consistency. Since then I switched to split for a couple years, then instinctive. Personally, as a hunter, I love the fluidity of instinctive on a good day. But I gotta say after 3-4 years of practicing strictly instinctive shooting with minimal improvement, my consistency probably would be better if I stuck with aiming.
Basically, what i'm trying to say is, I think a skilled &
consistent instinctive archer is about as good as it gets for hunting. If the individual archer can't make it work
consistently for him, I'd say don't be afraid to try something else just because of the "non-traditional" stigma. It's all traditional in my book.
