This is all really helpful. Thank you for taking the time to respond. Think I'm going with the tighter of the two. I still have my big 183 Volkl RennTiger GS board for the bigger, wider, less crowded days.... (Though, I say that now and probably won't ever look back given the reviews I have read of the Nirvana so far. )
Corey, that response nailed it for me. Part of my desire for a new board is to feel less stressed. My current board just seems like a lot of work...and you really have to let it run to be happy.
Thank you all.
