I'm hoping to get some information on the effects of tiller settings on cable movement and speed.

Background: I have a Bowtech Extreme VFT w/ a Shakey Hunter rest. The bow was set to ~ 60lbs. Unsure of the tiller, but the bottom limb bolt was about out further than the top. I had a limb bolt replaced and the bow ste to 65lbs. The shop set the bow to even tiller. Prior to the change out I had no problems, however afterwards I have been getting fletching contact. I've tried rotating the vanes, but the vanes just make contact in a different place. My rest is tied to the down cable. I am shooting the same arrows as before.

Any help in trying to understand or fix this problem would be appreciated. I am new to the forum. This will be my first year Bow hunting. I have been shooting since Feb. and have seen lots of progress, but this has put a damper on things.
