While I like the look (mostly for the distinctiveness) they are not my cup of tee to ride.
If it was such a great design why did it not last more than a couple of years?
I've only ridden a few though - Yeti, Alpinestars, Fisher, Nishiki, Saracen, and I remember they were all heavy and skittish due to the short back end and a little flexy under power - whoever said an ultra short back end is good for climbing has never ridden some of the silly steep technical climbs near me.
I've also seen a few broken Alpinestars, Saracens and a Yeti which would put me off.
Having said that I liked the roberts that was on here a few weeks back and I've also seen a dave yates which looked lush.
I would not go out of my way to have one but would love a good long shot to see what I think now.
