Hi Doc. Did Race Tech tell you the spring rate for those rears? Sounds like they sold you a race set-up. If you can let me know what they are, I may be able to help you get all this sorted out. If they didn't or won't tell you what the spring rate is, measure the outside diameter of the spring, the diameter of the spring wire, the total number of turns of wire from tip to tip to 1/4 of a turn accuracy (number of winds around the shock,) and the length of the spring when you are off the bike. From this info I can calculate the approximate rate. If they are way out of line, there are generally less expensive, softer replacements to be had.
I will be at Maggie Valley so we can tweak some then too.
