Weight its not a factor for me, the first couple tricks youll feel like you it holds you down but after a while you just get accustomed to it. Its only about 6 pounds more. It makes you do tricks faster and more powered up and thats always good, they look 100 times better. You kinda just grow with it. Just get a board with good amounts of rocker and above 136cm and youll love it, the thing of wakestyle is to do everyting super fast and powered so you need a big board with rocker that wont catch a tip or edge and faceplant on those super fast landings.
I think 132 is way to small to get the full potential of bindings. How wide is it? I wouldnt go smaller than 42cm. BIG board with nice rocker is the key!
