Firewire Addvance or Traditional Fun Board

Hi Folks,
I've been surfing for 2 years, 1-2 times per week excluding the winter. I'm a 34 year old male, 5'7, 150 lbs in better than average physical condition. I own one surfboard, a 9'0 Modern Longboard which is the only board I've surfed. As I am not good enough to pivot the board from the tail to turn quickly, a normal turn moves at the speed of a tanker. Eventually, I'd like to learn to ride a shortboard but I'm definitely not ready. I'm between purchasing a Firewire Addvance or a fun board that more closely resembles the shape of my longboard, just 12-18 inches shorter. Opinions?
