first off, try tgr, people here will recommend hellbents no matter what you say
Goats- good all mountain ski, slay pow, crud, groomers, everything, just a nice fat ski to charge and get real bomber days out of
Katana- basically a really fat mantra, so its got the burl but much more underfoot, it's a very good deep powder ski and does well busting crud also, but i wouldn't say groomers are its strong point, but if you've skied the mantra, it's very similar just super fat
EHP- good all around ski once again, but i found it doesn't really charge too well, it's got some burl but it's more geared towards short turns and to me it's an ideal touring ski, light but with enough meat on it to handle a lot
i think for charging the shit out of big mountain lines, look into the prophet 130, bandit b-squad, legend pro XXL, basically a super fat stiff as hell ski. for playing around in nice soft pow, maybe try something soft and fun like a bacon, but i find if you buy a ski for just that, you don't use it that much. as for all around, i'd recommend the goats or the prophet 100, i absolutely love my 100's, basically you name it except park and these skis rip the hell out of it, so there's my $0.02, but try tgr for a lot of feedback , i mean if you have someone here saying the scratch steeze is a big mountain bomber ski, you're getting misinformed
