FISH opinion

I have a 7'4 mini - mal, which i ride pretty much everyday lately. I also have a 6'4 - 21 - 2 7/8 modern fish. Got it to learn on but found the mini mal was...more fun!
Im 154lbs / 70kg.
I heard a fish (modern) that is too big is pretty much a "waste of space in the quiver". The shaper said it was a good board to learn on, and I did learn on it but I dunno....its pretty hard to dive under the bigger waves.
Whats your opinion? Can a fish actually be "too big"??
