that must be a very fast bow.......has he tried to down size on the pin size? i had the problem when i got a 3 pin sight they were .4...huge pins...went to a .29 for 20yrds and then .19 for 30 etc.....if only 3 pins i like the idea of 20, 40 ,60....then for a 30 yard shot it would just be between the 20-40 and for 50 yards between 40-60..
