Incidentally, I was told that you sail a viper single handed with a "uni-cut" sail. I just purchased the same sail for my Blade and I'm looking for some specs for Spreader Rake, Spreader length, Diamond wire tension, and resulting pre-bend to tune my mast for that sail. Would you be willing to share what specs you use?
Thanks,

I've got it set the same for both sails. I'll play with diamond tension depending on the conditions. I made a mark on the mast where the diamond wire enters for a visual reference for my max and minimum settings. On the bottom I'm running --(pretty sure)-- 26 on the black Loos gauge, and 34 at the top of the range.
My spreaders are set at 1-3/8", measured from the back of the diamond wire, to the luff track.
Blade might be a bit different, but probably pretty negligible if there's any difference in where the wires, and spreaders mount.
