Good review. I reviewed the Goliath. I would totally agree with you about the forgiveness of TBT. Personally, I did not like the lack of edge hold on ice. I found it much harder to carve and maintain edge hold. Other than that personal issue with the board, TBT is definitely a nice feel. It was super fun in powder.
I seem to have the opposite feeling. I actually like the edge hold of the ET better than the edge hold of a flat cambered board. But that doesn't matter, everyone has their own opinion
