Now a few things about that TNT base, which Lib Tech themselves claim is sintered here Lib Tech Snowboards Snowboard Technology
Sintered UHMW Base Material:
Super tough base material that holds wax well due to its compression formed amorphous polymer structure. Super fast when waxed with Oneballjay.
The TNT base is a sublimated base, which is why colors pop on their bases. The first article clearly states that extruded bases will NOT stand up to the sublimation process, which backs up Lib Tech's claim that all their boards have sintered bases.
Extruded base will not stand up to the temperatures required for sublimation
A five second search on the googlenet is a good thing, whether you own two Lib's or not!
