Glad you liked it! I'm a fan of narrow waists.
I also completely agree with Burton Bases. They are what I always compare other bases to. Burton's bases are very fast, have great wax absorbing properties, and also ride fast enough without wax. Their used up demo boards are always consistently smooth on the snow where others are slow. So since you've been an exclusively Burton rider, you're definitely jaded when it comes to bases lol.
