Hey Fellas, I am in the mood to pick up a new Gore Tex Shell and have narrowed it to the Arcteryx Alpha SV vs. the Arcteryx Sabre--Living in the the east, I don't have access to try those models on..so I am relying on any input you may have for me... I get out West to Ski maybe only 5-10 days per winter and and want this jacket primarily for Skiing while I'm out in Colorado. Otherwise, I will just wear it for as much as needed here around town when the elements require it. I am looking for something tough, which is why I like the alpha sv, but also with some skier-specific features, like length, powder skirt, pockets, etc. ------I think the Sabre is a little more skier specific, but also like the Alpha SV possibly for more year round activities.. I have done a fair amount of research on both- don't want the sidewinder or stingray, but will the Alpha SV "get me by" when I'm out West if we get powder? Is the Alpha SV long enough? I will also be layering underneath and kind of like the bigger cut to layer underneath--I don't have to have the powder skirt but like it for skiing-----please compare models if you have any experience---length? warmth? fit? features?
