My "profile" is virtually the same as pbartski except I'm 6'2" and 230. I've been glad to own every Legend ski I've owned most recently the Sultan 85 and would probably like the Sultan 94 just as much. However I don't need another "conventional" ski, I have the MX88. I'm looking for something with modest tip and tail rocker in the 185-190 length, but I don't want a 35m turn radius. Something "playful" for soft snow and trees yet doesn't get kicked around in the crud piles. Skied the S7 in 188 last week. Nice, but in the crud I felt like I do when I'm in my boat in four foot waves... Suggestions ?
I have skied all the skis you mention but one and I own the Motive 84. Here's my take.
Sultan 94 Conventional camber and conventional feeling on firm snow. This ski is great in crud, moguls, and soft-firm groomers. If I were going to buy a ski in this width as my only ski for the west, this would be a leading candidate. Roughly a 50/50 split between hard and soft snow bias.
Watea 98: Minimal double rise ski, very soft, fun, and easygoing. Very much soft snow biased. Probably not a super choice for your weight.
Rossi S3: Similar to above but firmer in flex and with a little more camber underfoot. The 177 is pretty solid for it's rather short length and running surface, skis very short. Unfortunately, the 186 has dramatically more rise and is actually less versatile except in deep snow.
Blizzard One: Minimal tip and tail rise, conventional but low camber underfoot. Quite grippy for what it is and very useful in both the 177 and 184 lengths. Skis short.
Motive 84: Very good ski for firm days but not what I'd travel the west with.
Ski Logiks: Have no idea.
So......The Sultan is the winner if you are looking for a more conventional ski, the One is probably the best choice of the "mini rockers".
