I've got an '08 Bengal. It doesn't have the STS system on it. A couple weeks ago I accidentally dry fired the bow while adjusting the draw weight. After looking over the bow, it looks like the only thing that needs replacing is the slide. I appear to have got off lucky there. The peep sight popped out, and a string leech I put in last year partially came out. I just pulled it out the rest of the way. The string and cable needed replacing anyway, so I'm not worried about that. My bow never came with the STS system. Since I have to take it in, I was wondering if I should order the STS system from Martin (#8897)? If I do I'll order the Easy Teflon Slide (#BP50) while I'm at it. Does the STS quiet down the bow quite a bit? How long does the bumper last?
