Btw you can use any board but usually a good tip is to check if it has insert for binding to avoid to destroy it.
I guess that if you are quite light (i'm 60) you can use virtually any boards.
I was using a quite flat board at the beginning, naish momentum, and now i'm using a cabrinha custom. I prefer the second one. With the first I had a good amount of speed and upwind ability and a very aggressive pop but the landing were quite hard and I needed to put ice on my knees after every session.
With the custom I found a little bit harder going upwind in particular with low wind but i've a lot of improvements with waves and chops and as the speed is not so high (I'll say more controlled) I can be more focused on the trick. The pop is super nice.
The landing are really soft now and due to the channels, even without fins or with short ones, I can control the board better (less slippery feel). And no more ice on knee after session
So first you can try with your board as long as it has good insert and i'll suggest you to demo board (a couple of session if you can) with high rocker and channels. Almost every brand has one of this board and there is a chart to see which one is the best for you. Used ones have a lot of scratches on the bottom and you can have for a fair price and brand new last years model are quite cheap too. In this case just check the reviews before buy.
Have a lot of fun.
