The only reason I have different set ups is because I prefer a longer ATA for 3D shooting. It' s probably more mental. Longer is more stable. I use a drop away on the 3D and a Bodoodle on the hunting. I still shoot fixed pins but different styles. Toxonics Hybrid V w/ 9 inch bar for 3D and a Tophy Ridge Matrix for hunting. Now the truth, I have two set ups because my wife doesn' t know yet!
