I know this much, in 1996 dan evans was working at an archery shop in spokane and was building fall aways from all the different brands for the customers of the outdoor sportsman. I called BS for a couple years before that cause I had the fancy mathews rest and was convinced that I needed to have launcher pressure and all the tuning mumbo jumbo from way back.......well you see what is going on today. for those of you that don't know dan is the owner of trophy taker and has been building these rests longer then anyone. that is why he gets my $$ now. funny, he used to make $8.00 an hour and begged people to buy into his idea.....claimed it would change archery forever. whoda thunk it.
