4frnt durability

I don't like them. I had a pair of TNK's from last year and broke them in one season, cracked them in the first day of use, but by the end of the season they were beyond use.

I bought 07/08 TNK's at the beginning of last season and rode them everywhere last year. I loved em, very solid park ski. Got one core shot, no edge cracks, but significant topsheet chipping.

Upon further review, I discovered 7 edge cracks. Oops

4frnts have been hit or miss for me over the years. ive owned 3 pairs. ive had some that were absolutely bomb proof, and others that fell apart the first day in the park. granted, that was before they switched manufactures, but yeah, the durability is questionable. however, to counter that, every 4frnt ive been on has skied fucking awesome. definitely some of the best riding skis ive ever ridden. so yea. if your looking for a ski to keep that long, check out liberty. ive heard lots of good things on them (never ridden them tho), and they have a 3 year warranty.

I broke 2 pairs of STL last year, within like 4 days skiing them

Their park skis are a coin toss, and their big mountain/powder stuff is awesome.  All of them ride amazing though.

i have 08 vcts, the only bad part about them is that they chip really easily. Mine have some big chips along the sides but besides the top sheets they are pretty good and they might have improved the top sheets since then also.

i don't think a ski exists that will last you 4 years man, unless you never set foot in a park. you're damn lucky if you get more than 2
