I do like the Exotics and I think they'd be a good choice. Off the top of my head, 395mm axle-to-crown would be about right if memory serves. (and you're right - I don't think I've seen unthreaded Orange (R7) forks, so you're probably wise to go aheadset if you can for your purposes).
I'll put some air in the superfly's and see how they fare with some new tyres as well. The Exotic's might have to be a long term goal at £80. The forks on ebay are listed as 390mm in length, which i assume is referring to the axle-to-crown length, so those will be the ones.
Thanks for the advice!
