Recently I have been thinking of having some fun experimenting and trying to shape my own board. I am 15, 5'8, around 120 pounds and have been surfing around 5 years. What would be some good dimensions for a high performance short board that would have good speed and that I would be able to pull some radical tricks like aerials on? Also I live in Cocoa Beach, Florida where there is a lack of quality waves if this matters.
