Reviving this thread as I pulled the trigger on Tackla 9000 pants recently.
I'm almost 6' - 180lbs. Went with Med-50 Tackla size. This thing fits like a glove. My issue with other pants brands (CCM-BAUER) was the fit was too loose on hips and thighs. Pants felt unstable when skating at higher speeds.
Quality seems pretty great for a $119cad pants (regular price advertised $200).
Got to say I'm super happy so far. Protection is generous on hips but not annoying at all. Probably not the lightest, but weight isn't an issue.
