i have a Sabre SV right now and its my favorite shell so far.... personally i don't like the hood/collar style of the stingray although i do own some jackets like that..i also wouldn't buy one with insulation - but that is just me and where i live and what i need it to do for me...
if you live in a wet area, do not want a wet ass ever, or would rather have your pants last 5-8 seasons instead of one or two - then yes, they are worth it
all this stuff is great for the resort, if a little overkill for most people - where it really shines is hiking, and in the backcountry. plenty of people who only ride resorts use it tho, so don't feel weird about getting the most hardcore shit if you want it, can afford it, and just want to be comfortable all the time with out having to think about it.
EHHHHH, the real snowboarders snowboard in a hoodie and some jeans. UMAD?
Im just kidding, tho i really wish i could afford something like Arc'teryx or even something that is above 15k rating
