Excellent, Excellent, Excellent video!
I started experimenting with stringwalking and the fixed crawl last year. I am shooting better than I ever have in my 40+ years of seriously shooting a bow.
For those that don't want to consciously put the tip of the arrow on a spot, but prefer to pick a spot instead and focus on hitting it, most will find using a fixed 25 or so yard crawl will increase your accuracy shooting that way also due to your gaps being smaller.
Another thing I have found with the fixed crawl is you can cant your bow and shoot a fixed crawl. I like canting my bow and I have found within hunting ranges I can do that very successfully.
Thanks for your effort and time in making this video. It will help both beginner and experienced archers alike...
