I got the Specialized BG2 Sport MTB & after some serious wrangling with the bolt that kept that evil Bontrager on my bike, I got the new saddle swapped in. Went for a 1.5 hour ride today on it; I definitely prefer it, though can't yet say that I like it: thankfully there's none of the pressure on my soft tissue, but the sit-bones were a bit sore (but are not, now). We'll see how it goes after a few commutes. Thanks for the advice, everyone! Happy cycling!
