Both are good stabilizers and if you have the opportunity to try both, do it. As Matt alluded, what works good on one brand/model of bow may not be as good on another. I shoot a Hoyt Ultratec Cam & .5, and feel a Doinker does a better job on my bow than a Stealth does. Stealth stabilizers seem to be real popular with Bowtech shooters. Hopefully some Mathews shooters will chime in on what works for them. I picked up a 7" D2 Multirod Doinker from the classifieds really cheap and feel it is the cream of the crop in the Doinker line. BTW, every time one of these threads comes up I'll pull my Stealth out of the drawer and compare it to the Doinker, just to make sure I'm not missing something. In the end, the Doinker stays on the bow.
