Help me choose the right wakeboard!

Hey guys i am looking into buying a new wakeboard but i honestly have no idea where to even start...First off, i am around 5' 8'' weighing around 150 and id say i am a pretty aggressive rider. I really progressed this year with the purchase of a wakeboard boat. I can go wake to wake very easily and consistently throw heel side backroll's. I am looking to replace my CWB board (not sure the model) because i feel as if it may be a little to big for my size and i am tired of the uncomfortable boots. I dont think my feet are growing anymore so would you guys recommend some "snowboard" like boots? Any suggestions on the type of board to get? preferably the budget is under $400 if that is possible. Point me in the right direction please. Thanks for any help!
