Scott,
No way could I use that seat..too high, non adjustable, no padding....
Idrod,
I have one just like that Extreme 2000, it collapsed on stage once, I went right on my butt, got it welded and still although not bad, less then perfect.
This model Quik lok is what I was thinking of .....gary ordered one and is waiting for it to see if it does the job for him.....then I can see if it will do it for me also....if not I'll keep searching.
