I have a custom made one on order for my Allegiance. I see the advantages and enough people out there do as well. If I do lose a couple FPS, so what. I'm not too concerned about that. I'm more concerned about the quietness of the bow. I have heard that tnew EDS stopper used by STS, as well as the guy who made mine, is a lot quieter and more flexible. The older version would create a "slapping" noise when the string hit it.
Also, Hoyt started using such a device this year on their bows. I'm not saying Hoyt is the authority on everything, but their engineers seem to do a lot of good work when it comes to bow design. If they use it, that makes me confident enough to think its worthwhile.
I have a new Hoyt Vectrix with the new stealthshot; similiar to the sts. works great, very quiet. Another item that people overlook andmakes a bow very quiet is rubber cat whiskers on the string. I put these on my old Trykon and my current Tribute and it really made both bows very quiet. Total cost is $2.00 per bow, try these 1st before spending $ on a sts.
