Roto Corking is the best way to apply fluorocarbons. It is easy on the base, quick, and results in the fastest finish except in dirty or aggressive snow that covers a long distance.
In powder or non-transformed conditions, a rotocork applied fluorocarbon ski is faster than an ironed-on fluorocarbon ski. This is why JetStream Moly rotocorked over Dibloc HF Blue is such a common wax tip for cold snow. There is nothing better!
