backflip is much easier in my opinion. i have never successfully landed a frontflip.
for a backflip, get a jump with a lot of kick and wait until you're at the very top. once you're there, pop fairly hard with the kick of the jump and you'll flip. if you can do it on a tramp, you can do it on skis.
for frontflips... i don't really know. haha. i've tried a few and never actually landed one, lol.
