I have my eyes on these, hoping to find them in the spring for cheap somewhere.
Can you check the dimensions again? The Scott website says 181 is 134-104-123. When I looked at a pair in the shop I recall 137-107-??? in the 181. (It looks like they've updated the website now, instead of having the dimensions listed for each and every length, they only have them for 1 length). I do remember the 191's listed at 138-108-127, as it says on backcountry.com
Can you take a picture of the dimensions listed on the ski, and maybe even measure them yourself to compare? I'm very curious about what the actual dimensions are, now that I've seen 3 different sets listed.
Perhaps they stamp the dimensions of each individual ski since there can be a few mm's difference...
Definately look like sweet skis, I'd love it if you could do a detailed consumer gear review here to see what you think. Search TGR for all of my posts (same name, I don't have many) and you'll find a couple threads on them with a few impressions. Some say it's a noodle, some say they're sweet.
Other neat thing I've noticed with them is that the topsheets are different between 181-191. The graphics are the same, but the 181 is a pretty standard topsheet, while the 191 is sort of holographic (don't think anything really moves on the graphics, but it has a different texture and appearance.)
Definately some sweet sticks there, I'm thinking they'd be perfect for a heavy touring setup with some Naxo's. The 3-4 mm discrepancy seems to be a much larger gap in my mind. I just can't see the 107/108 waist being as versatile here without the constant deep powder as the 104's I have now. I'm curious to see what you think about them!
