Recently acquired one (with Bassara R flex shaft) off eBay. Had my fitter shorten the shaft to 38.5" and set the Surefit to B3 (which is what I determined best with my other clubs). Took it out and smacked it at the park. I would say I gained 10 yards vs the Superfast 2.0 6-27 I had and it almost hits as far as my 910H 24*. Very easy club to work (was choking down, hitting pitch shots and so on).
I have it set up as a 6H (with the B3 setting).
