I'm personally in the upper 80 buy category at the moment and have been considering the IM88, Mythic Rider, and the new Bizzrd 8.7..
For me I need something that can kill everywhere, especially in the crud.. I have Goats for the big pow days and Tiegershark 10's w/switch for the groomer only days..
Me 5'11- 180lbs level 8.5-9. I am REALLY looking at the new 8.7 hard but am waiting on further reviews/testing etc.. Sounds like a phenominal ski, but how does it do in crud? Dimensions would indicate more of a frontside carver than backside crudbuster.. Any and all info anybody has would help..
All-mountain ski with sidecut, race-like all-mountain performance:
Blizzard Magnum 8.7 174cm (similar in feel to the Elan, smooth, powerful, snap)
Elan 82ti 176cm (probably my favorite mid-fat tested all spring: a truly impressive ski)
Fischer Cold Heat 170cm (skied a pair all spring, best in shorter lengths, powerhouse carver)
Head iM78 177cm (tons of stability in a long length, can handle any condition including 16" of new)
All-mountain ski with less sidecut, more backside oriented:
Head iM88 175cm (damp, smooth, powerful, solid carver)
Elan 888 177cm (lighter in weight, energetic, stable, powerful, solid carver)
Stockli XXXL 178cm (most powerful ski tested, no speed limit, no bumps)
Volkl Mantra 177cm (great crudbuster, smooth, poor on groomers, no bumps)
I would happily own any one of these skis: it would be a coin toss between any one of them. Those skis that are in the first group are still great in crud, but rip groomers more aggressively. Since you have Gotamas, the first group of skis has more of contrast in feel. The TS10 may become redundant, and you might want to trade it in for a true hard-snow ski (the TS10 is very versatile but not really a race-bred ski). If you want more power, the Dynastar 4x4 is a pretty incredible frontside ride: certainly lacking the TS10's versatility, but blows it away on groomers and hard snow.
