Although those "bats" don't have as much material hanging out as far as regular Sims Leeches do. So there may be a trade-off there in that it may not dampen the shot as much as Leeches, but may last longer?

I dunno- I haven't had a problem with Leeches at all. In fact I can't believe how long they've been on my bow with thousands (yes I mean thousands) of shots. I put them on last July, shot with them for hunting prep and hunting season, and then used that same bow over the entire indoor target winter. Over the winter I was probably averaging 1000 shots a month from that bow. Leeches are still there- but I see that one of the tips has broken away recently.
