I agree that duct tape should be a last resort Im not into Macgivering my boots. But i think ill order some anyways just because I feel better with the metal ones. Ouch I need 6 buckles at $20 each thats $120 just on buckles. Should I just wait for next years redesign and hope they are backwards compatible? Oh and just because I don't feel like making bother thread, I have flex 4 tongues right now, but I'm going to be going on a trip to BC and some decent skiing what flex would be better 6 or 8?
