My old Butterfly Century gave out after 6000-7000 miles, so I bought a new one. I've tried a few other seats, but then I go back to my Butterfly Century. The Poron XRD does actually absorb shocks, and the fairly wide cut-out works well for me.
I have spent a lot of $$$ on trying many saddles. This ones the charm for me. The Sele Italia Diva Gel flow is a close second. Have done multi day tours in this saddle and done well with it. I do find that I am hard on saddles and have to replace them every 1.5-2 Years. I like that this is not leather and lasts longer for me. No wear holes like I get with leather saddles.
I put this saddle on my hardtail because I'm doing the Dirty Kanza 200. I need something that is going to get me through the whole ride. So far I've been on 3 hr rides and it feels good. Terry saddles have always been my go to saddles and never have I been unhappy with them.
I use a lot of Terry products, this is my second Terry Saddle. I tried others but couldn't find the comfort of my other Terry saddle. The Terry Butterfly Century was an improvement over my Terry Ti Butterfly for me
