Ok, think about this one for a minute. If a bow shoots better maxed out, why would target shooters fine tune their bows by adjusting their limbs? Any kind of tiller adjustment is going to affect that. You can't tiller tune and keep your limbs bottomed out. I have shot my bow either way, maxed out and set as low as it goes. Shoots the same either way. If you think you want to shoot alot, you may want to go with a lower poundage any way. Less stress on you and the bow.

And my bow geometry does not change according to where I set my limbs. My ATA and brace stays the same even with 4 turns out of the limbs. And as far as I can tell my draw does not change either, maybe about 1/8 of an inch, I would have to measure it. The important thing is to take the same amount of turns out of your limbs and check the tiller when you are done. If you don't back the limbs out an equal amount of turns it will throw you tiller off, which will effect your nocking point. That is good way to make minor adjustment to you nock point by the way, take a half turn or so out of one of your limbs and see how it shoots(called tiller tuning) You can also correct spine issues by adjusting your limbs.

Keep in mind any time you change anything on your bow, you should check the tune, if you fine tuned it for 70 lbs and then turned it down to 63 or something, you may need re-do it again. I sometimes wonder if this is the problem when I hear people say it effects how a bow shoots. Maybe they just cranked the bow down and fired some arrows thru it and said, "Hey, it shot better before!" In the mean time, the bow might be out of tune, there is less holding weight which changes your grip pressure, and the spine of the arrows may have changed. No, it must be that these bows are built junky and have to be cranked down tight in order stay together, that sounds better.

My bow also does not make any more or less noise when the limbs are turned out.
