Yes, for two reasons. One is that I think the Butterfly bridge is sketchy. My first one fell apart with less than 20 hours of climbing on it. It was still intact, but the shrink wrap rubber thingies that hold the cover came off, and it was no longer smooth. The ring would get hung up, etc, it sucked.
Second reason is when I want to shorten it, I have the Tachyon piece that I can undo and shorten. The second ring is for second TIP's.
