Len, I may already know the answer to this, but since you're the guy I look to for these sort of answers I'll ask.
How many twist does it take to really mess something up? The only reason I"m asking is that I put one twist in my string the other day to get my peep to line up. I read through my manual carefully and this is what they recommended.
On another note, I have been shooting my Allegiance for about a week now and everything seems to have settled in nicely. The strings and harnesses seemed to have stretched a very very small amount, but I attribute that to settling more than actual stretch. What I noticed is, that my timing marks on the top and bottom cam have moved exactly the same amount since I got the bow. Looks like this hoopla of equaling each other is holding true for these bows.
