threads but my take on front flips...
i feel like just about everyone and their dog can do a front flip into the pool off the side. what makes that any different than a knuckle? to me, on skis, theoretically, it should be easier because 1) you are moving forward and the landing of the jump drops out from under you as you flip allowing for more time to rotate all the way to your feet 2) you get extra pop when loading the front of one of your skis and 3) worst case scenario in trying your first front flip, you slightly under-rotate and slide down the knuckle on your back, but what makes that slide any different from trying spins and not landing those then sliding down the knuckle. i say it just takes some sac up and go for it.
but be smart about it. my $0.02
