Not sure...tell ya the truth, I've not done research on Ellsworth b/c they are kind of an "untouchable" for me. I'm more of a blue collar MTB'er. There is a guy around here who has 2 of them and they seem to rAWK pretty hard.
If you are looking into Freeride and Slalom...the Eastern Slash 5" has been blowing out cheap lately...Jenson had some great deals for a while. It has an Ellsworth swingarm.
Anyone?
