Deadbolt
I've shot a few long bows and have found that the three piece take downs seem to shoot a littel nicer, no hand shock. I have had a couple of A&H's hard to beat, but they only offered one type of grip, it didn't fit me that well, so I tryed a Morrison, low grip and that worked for me.
I now own two Morrison's low grips (A) riser and (B) both 64" carbon foam core. I have not shot a Centaur or Shrew, but I'll bet they shoot good as well. It's a hard call with so many good bow's out there.
