Warrior girdle shells run a little shorter, if you want pro stick there's a seller on SLS with a bunch of the "new" pro stock Warrior girdle shells which run much smaller than they used to, so if you were to get a L in that it would prob fit more like a medium length wise. With CCM shells (PP90/PP9K) I've found little consistency in sizing, I have about 7 or 8, all medium, and maybe 2 are the same, the rest are shorter/longer/wider/etc., it's a crapshoot. The Tackla girdle has nice kidney pads so you'd even be fine with a pant shell rather than a girdle shell, the pant shells are usually just a little more roomy/boxy so if you sized down in that it might work out well length wise and have enough room.
