07
VX7R, I did actually drive both of the sleds you mentioned and prefered the RTX ( I ordered a 07 RTX). Had a 06 Attack last year and it was way to soft for my riding style. I too plan to stretch the RTX to 136". I think you'll be happy with the floats, I felt the front shocks on the Attack were a bit soft when launching off of high speed rollers in the trail the sled would bottom hard.
Good luck with your project...
