I have the Terry Fly on all my bikes. It's basically the same structure and padding as the butterfly, but it's narrower. The butterfly was too wide for me. I love the fly, but I agree that they breakdown faster than I would like, especially when I only had one bike that got all my attention!

I think that if it had slightly less padding, I'd be even happier, but for now, this works for me. It's the only saddle on which I've been able to comfortably ride centuries and then ride the day after with no soreness.
