Another board buying question

I know there is about 8 million of these type questions on this forum but I am looking for a little insight in purchasing a new board. About me, I am 5'9 and weigh about 210lbs. It is my first year into wakeboarding and I have been riding an 07 Ronix Vault 144cm with Divine bindings. I was having a difficult time getting very far over the wake on my jumps. So I decided to rent a performance board and see if it would help.

Well, I rented a 2012 LF Watson Classic 142 with some Watson CT bindings. My pop over the wake increased alot. Now I am almost going W2W on the rented board. I love the feel of the board/ binding combo. My question is, I know I am going to stick with a nice pair of closed toe bindings, but should I try another board or two and see how it feels before purchasing the Watson Classic? The guy at the board shop suggested I try the LF Harley. Anybody have any experience on the Harley?
