I got to demo the iSuperShape Magnums (the Green ones) vs the iSuperShape Titans (the Blue ones) on Turoa a couple of weeks ago. I have a pair of 05 SuperShapes as my normal skis.
The snow was typical Turoa spring corn, starting the morning as yesterday's frozen slush, groomed, hard & very icy. As the sun hit the slopes (there are NO trees on Mt Ruapehu) the snow softened quickly and turned to slush by the end of the day, to freeze overnight & do it all again tomorrow.
Both sets of skis were 170cm in length.
I'm male, 95kg (210 lbs).
Anyway, my thoughts.
1. Both new KERS skis will give you grief if you ski in the back seat. Neither are very forgiving in that regard. Both force you to ski in a good position, or you end up feeling like you are going to fall (or you do fall).
2. I skied mainly on groomed (see above) trails mid morning on for about 1/2 hour. The narrower Magnum was much closer to my now old SuperShapes. The biggest change was the feeling under foot, where I could feel where the edge of the ski was. On the Magnums (71mm underfoot) it felt much closer to holding an edge under the boot, just like on my SuperShapes (68mm underfoot). On the wider Titans I felt like my foot was elevated off the hard pack icy snow, which was a completely different feeling. My centre of balance and contact on the snow felt like I was skiing a couple of inches outside of the outside of my boot. Weird feeling.
3. The Titans gave my a lot more confidence to ski off piste, onto a bit more challenging terrain, whereas the Magnums felt like a much better, but newer version of the old SuperShapes to be used on groomed slopes.
4. Both skis held an edge on the hard packed icy snow that Turoa throws up regularly - I think Turoa is similar from the descriptions I've read on the forum to the New England ice pack. My SuperShapes are now struggling to hold an edge on the same slope, having demo'ed the new skis then jumped back on my own just confirmed the feeling.
5. The KERS gives a huge amount of energy at the end of a turn, great feeling when you get it right.
If I was going to ski on trail, then the Magnums would be my choice.
If I was going to look to ski more off trail then I would consider a shorter (maybe a 163) Titan.
Hanging out for an end of season sale...
