ok lets see. the bow is new. it was a floor model at a local sporting goods store. the only blemish on the bow is a small scratch on the upper limb from the store manager carelessly hanging the bow on a metal hook. but the scratch doesnt go much deeper than through the camo finish. PSE says that the a-t-a should be 33 1/8. I come up with 32 15/16 from center of one axle to the center of the other. that difference might be due to the fact that i have the string slightly shortened by hooking the string on the shorter post on the upper cam. As far as the tiller, i dont know too much. i originally tried tuning the bow with both limbs set at their maximum of 70 lbs. I have tried relieving the upper limb as much as 2 1/2 turns in an attempt to change the tiller. it didnt seem to make much of a difference though. the timing of the cams seems to be good too.
