I weigh 140-150 lbs and normally have great fun with a pair of 165 cm 4x4. It was dumping the last two times I went to Mammoth, and I found out that I had to be very careful to avoid sinking the tips and got stuck on flatter slopes. (I was surprised that my old Metron B5 was better in the deep, heavy snow.) I suppose I will have a lot more fun with wider skis in such condition. I want something to complement the 4x4 off piste but versatile enough to have fun on groomers or when it hasn't snowed for some time. I am thinking of the Mythic Rider worry that it may be too similar to the 4x4? Other possibilities are Watea 84 or Watea 94. Which ski and at what length would you recommend?
