Originally posted by Shawn Leonard: I believe you can tell a difference on tiller. I can for sure. Usually a bow tillered for split need a much higher nocking point to tune for 3 under and the bow will be noisier, if tillered for 3 under the bow will not require an unusually high nocking point and be quieter as well. I used to shoot both once ina while when I had a close shot of 10 yards or so I shot 3 under and gun-barreled. Shawn
