This probably isn't worth a thread, but maybe will save someone the needless annoyance I have had for the past week or so. I initially set my new Z7 to 50# draw weight and zeroed it at various distances. Last week, because my strength had improved, I reset the draw weight to 55#. Today, I reset it to the design weight of 60#. To backtrack: Since the first day I fitted my bow sight, I've grouped consistently to the right (left handed shooter). I ran out of windage adjustment and had to reverse components in the sight in order to gain more. So, I finally had it zeroed at 50#; last week I lost that zero and again grouped consistently to the right. I readjusted the sight for zero. Today, I lost that zero and yet again grouped to the right. I know you are way ahead of me on this: The shift to the right coincided each time with increasing the draw weight. For some reason, probably because the bow is so forgiving otherwise, I had not realized that a change in draw weight would require re-zeroing the windage. That's it; a couple hundred arrows shot because I couldn't believe what was happening and wasn't smart enough to stop and think about it. Harley

You may think this is not important but I disagree. This simple conveyed information to someone with basic archery level/skills will save me some grief when playing with poundage down the road. This info is noted and Thanks for sharing.

Deadeye, I'm not sure your reference to "rotator" concerns my torn rotator cuff, but for what it's worth, I didn't sleep well last night because the extra pull at 60# inflamed the joint. I'm strong enough, now, to pull the bow but will have to pay for it. I do gain 11 fps over 55#, but 294 vs 283 probably isn't worth it.
On the other hand, at 294 fps I learned that I can set my slider to 30 yards and be only two inches high at 20 yards and ~seven inches low at 40 yards. That looks like a good deal for treestand shooting.
BTW, I didn't have to change arrow spine from 50#-60#.

i was funnin w/ you on all the shots,///regarding spine, poi & papercuts will change w/more 0r less w/ lbs changing much like rifle reloading & adjusting weights & watching changes when developing loads(the harmonix is in the arrow). i do know of a gentleman which is approx 60yrs of age which in his prime shot 105lbs & 2419's,today he is shooting just 50lbs & @5.0 per lb & the right arrow selection is amazed he can still do it all effectively,im next!! ;D ;D//hope well for your rotator
