Run away from there ASAP. He is trying to get you to spend the cash to buy a new arrow rest. I went to a fall away and got 1FPS. 1. Now if speed is a consideration, get rid of weight on the string. i went from metal nocks to tie on nocks and got 8 FPS.

A friend of mine used to use the 3 prong tiger tuff sure shot rest, (similar to the bodoodle). He had his bow chroned with this setup (last year). He recently put on the drop zone fall away rest and chroned it (last weekend). He gained 10 fps. Seriously. The only thing he changed on his bow was the rest. Thats it. The thing that doesn't lead me to believe that he gained 10fps, was that 2 different chronos were used. One could have been more accurate than the other. He did sight in his bow when he got home and said he had to adjust his 30-45 yd pins.

gained 4 fps with my FX when I changed from the Quicktune 100o to the QT-4000. It is worth the change though . . . accuracy can be a greater than the speed gain and that makes the offset worth it to me.
