I don't think you can go wrong with any of these. I've always heard great things about the Gotamas and it is always well reviewed but I can't speak to it myself. I have a pair of Line skis and they are great, the Prophets are a solid ski. The Helix has more flex than the Prophets so if you like your skis stiff go for those. I've heard lots of good things about these Helix's - from some ski instructor friends. What you should really do, is check Tramdock.com for the Helix skis to pop up again - they were like $250 - that's a decision maker right there. :) (Check out TramAttack.com for Tramdock history...)

These skis are pretty nice skis, and can definitely handle the whole mountain. The Prophet 100's would be another good option, but a little less float. Gotamas are sweet skis, everyone loves them, including me. As another option I would suggest the K2 ObSethed, the rocker helps you float so much, and still handles hardpack and groomers like a carver, with a little chatter though. I would say that these, or the K2 are the best options, then the Gotama, then the Prophets.

I would go rossie--- fatter, quicker, one of the best non-rockered powder skis out there and just a real fun ski all over the mountain not just in pow.

If you mount a Dynafit, first find the balance point of the ski and see where your boot center would be by lining the front holes of the boots with this point. Your boot midsole should be behind the standard mark on the ski. Then measure the distance between your boot center and the standard mounting point on the ski and divide by 2. Then put your midsole of your boot forward 1/2 the distance you measure, and it should be where it would go. It works great if you do this because then you are close to the pivot or balance point of the ski, which is recommended for dynafit, and close to the standard mounting point for your boot midsole. If you have any questions, email me at rene@libertyskis.ca.
I have mounted a few of those with dynafits and find this is what works best. If you are a 26.5, your boot midsole would be about 2cm behind the standard mounting point and your toes would be about 2cm in front of the balance point of the ski.
Great skis to be mounted with a Dynafit as they are so light.
Cheers

You won' t notice the width at all, just the extra stability and dampness they provide. I went from a 90 waisted ski to a 115 waisted ski and was blown away that to me they felt the same on groomers, but floated like a battleship in pow.

It is softer then the prophet, no metal in it, it will ski fine switch as it is not as a directional ski as the 100, I don't know the mounting point of it, but you could shoot an E-MAIL to liberty and they would let you know, I would go 4-6cm back from center to make it a better all mountain carver, deff an all-mountain ski, have fun.-once again gracias willie

Hi henry- The helix is a great ski, i didn't suggest it because, when you were looking at the kung fujus i thought you were going thinner, you are correct it is a lighter more playful ski then the prophet, Powder mag has been raving about this ski for 2 years, and nobody has caught on yet, kind of like line skis until k2 bought them 2 years ago, now everyone is interested, they rip groomers and blast crud, they are not as quick as the prophet because of the turn radius, but you won't notice to much difference because their softer and livelier because of the bambo core, great choice. I would buy these over the prophets in a heartbeat, why more fun ski.

I can say that i have skied the P4 and totally loved it. they look similar. and i am impressed with the eco-friendly aspect of the Helix. i don't think you can go wrong. so with many days on the P4 i can stand behind them, that said i am all about trying new skis (adding) The p4 is a good ski but i had some things about it i did not like, its heavy, the tips are stiffer then the tails which is good for busting crud but felt like they wanted to washout at times, also it does not feel like other twintips, what i mean by that is that it feels like a convectional ski that happens to have a raised tail. The helix is super light and playful, with a lot of energy do to the bambo core.imo they blow the p4,s out of water. But it boils down to how you like your skis to feel, if you want a ski that feels like a gs ski, damp, but solid go p4, but if you want a playful, lively ski,that goes anywhere including park go helix.^ I demoed both of these (actually I borrowed a friend's Helix, but I demoed the P4) and they are both awesome. The Helix has a faster camber/decamber response, and I find that I can ski it better, faster, longer in the powder. The P4 was a little stiff for me (I weigh about 175) at the tip and tails. The Helix held the edge when I was out of the powder. You probably can't go wrong with either one, but I like the Helix better.
