I have to agree with you Matt, the limbsavers made absolutely no diff. compared to the Bowtech blocks, I've been considering the ultras myself. Stealth is the brand name,the Stealth Hunter is what I'm useing and I tried some other stabs that I have and none of them even come close to the Stealth . One thing I forgot to mention, keep an eye on your module screws they tend to loosen up if you don't loctite them.
