If you ask me, I'd say "man-up and go rigid". Probably the wrong answer, which is why I'd suggest asking this same question on the mountainbike forum here, or on the other forums. (Won't say which one, but it rhymes with empty-bee-yargh.com)

That being said, it's been years since I cared about suspension forks, but when I sorta did, the SR stuff was considered kinda wretched. Perhaps they've improved since then, though.
