Well, S-dog, I finally got the Koobi Si, and rode it for the fifth time today. The jury's still out. Initially it felt good, but wasn't set up right. I have been tweaking and fiddling with it every day, and still haven't found saddle nirvana. It is better on the girly parts than the Terry Butterfly I was using, but I find I keep moving around a lot more, trying to get it 'just right'. So I'll fiddle some more, and hope to get it right.
