I have a REV 162, 3pitch, and an Everest 154.
I loved the 162 in the deeep and it was ok in the medium pack also, but....pushy in the set up. You always had to break the track free to slide around in the set up...
The 154 is more nimble, especially in the spring, and unless it is 4 feet of fresh, I would rather ride the 154.
Eludnu hit it on the head,
Some people say they just ride 4 feet deep, all the time.... I say BS. I get maybe a weekend , maybe maybe 2 weekends of stupid deep.
X2!
I'm picking up my 154" XP tomorrow.
