Hi Ray, the plates are 4mm thick so you'd be at -1.5mm with a front plate, and +6.5 with a rear. I think the skiing is fine at +6.5 but if you want to get to zero you can add 6.4mm classic shims which would do just that.
Hey Jake, I would say large would fit you better, the sizing is fairly Euro. They stretch well so the medium probably wouldn't be grotesque but could be extra tight in the lower half.
Hey Elliott, unfortunately Dynafit didn't bring this pole into North America this season, only the PDG for racing.
Welcome Peg, I will send you an e-mail to learn a bit more about your plans & style before giving a recommendation.
Hey Mark, from a pure skiing standpoint the 177 is still good for you. Lots of folks (including myself) shave some centimeters for mountaineering though, as it is more manageable for all the non-skiing parts (and some of the tight skiing). Since you're also using it at the resort, I think I would stick with the 177.
