Replying to Making Tramp Skis

OK i have a pair of really old k2 slalom racing skis. they are like 210 cm. i planned to just take out the edges of them but should i still duct tape them? i figure you take the bindings off right? but then how do i hold my shoes to them? also, what is a good/cheap way to cut down the skis to like 170?

Doesnt matter the size u ski, doesnt matter what type u ski, only matters how hard u ski, and your love to ski
