Replying to I want to rocker my TNK's

so, last year i got a pair of 4FRNT TNKs and they are probably the best ski i've ever skied. But after a year of rails, kickerlines and what not they are totally beat up. The edges are starting popping out in the front and the back, this could be fixed temporarly with epoxy which i've done quite a few times now.

A while ago i read here on the newschoolers forum that alot of pros heated up their skis and rockered them on their own to get more flow in the powder. Does anyone know how to do this without risking the ski to go up in flames or something like that?

The reason why i want to do this is basically just because it sounded fun, and now that im soon to be sitting here with a pair of skis im not going to use i might as well try this!
