just going on what people have said on this forum, the proto is said to be suprisingly light. pretty sure the t. rice on the other hand is relatively heavy. supposedly that '12 rook is pretty light too.
Yeah I am down to these 2 boards, the proto or rook. I have had a proto in my hand and it felt light, didn't have a 12 rook to compare it to. Hopefully I can find a shop that has both boards in stock.
