What do you guys think of the 9,1 Y

I’m thinking of the 9,1 Y to make a speedy 9,0 longboard, something that can race down the line and pull into the barrel (but still qualify as a longboard). I am thinking of pulling the nose rocker down 1.5 inches from center. So, any advice? Suggestions?

I’ve shaped 3 9’0"s using the 91Y and all have been great riders. Although it was a 91Y, it had a slighty modified rocker, what Clark calls “bottom centered”, something like +3/4" nose, - 1/2" tail rocker.
