Yes, just wondering if it makes sense to fork out the extra moolah, or is the difference really miniscule
The Core of TBT will not change. This is a nuance improvement on an already refined line. The ET Classic is not changing at all for 2012 (including graphics).
Consider this: TBT basically combines two profile technologies. The boards are cambered on the center base, but if you were to follow the edge line, they are Rocker-Camber-Rocker due to the TBT lifted edges at the tips and tails. The newest TBT brings this further around the tip and tail, but they were already raised.
