IMHO, Trues seem to play in the middle category in terms of flex (when comparing to other mid kick sticks at the same flex). I find Bauer to be touch stiffer than True, CCM to be noticeably stiffer than True, and Easton to be whipper than True. Can't speak for other brands.
To the OP. I agree. I typically play with the CCM Tacks line at 75 flex (cut to feel like 80 flex). With my True XC9s, I have both 75 and 85 flex, and the 85 feels more similar to the CCM 75. The 75 True is definitely whippier.
