TNK's and Click's aren't even comparable, and neither have a record of durability.
TNK's are fast, stiff-ish, and awesome. Until they break, delam, chip, have the edge rip out, or one of the other 100 things that always seem to go wrong with these skis. I had 2 pair that delamed within a week. Pathetic quality for a park ski. Click's are similar in durability.
Bottom line: These skis are always cheap and on sale at the end of the year. It's because no one wants them, and 4FRNT isn't exactly the most awesome company to deal with when they break. They've done some shitty things in the past....
If you want park skis, look elsewhere because only 4FRNT's big mountain stuff is worth your time.
