Next shortboard?

Howzit,
Heres a little background of my surfing history:
-I've grown up in a small town, Nanakuli, on the west side of the island of Oahu. Our whole coastline has some nice breaks but my main break is Ulehawa, a shallow reef break that barrels like pipeline (locals call it mini-pipe) when the right swell hits it. Winter time this break is one of the best imo, also there is practically no crowd here. For example, one morning when I went out, the waves were 5-7 Hawaiian height with perfect barrels. For three hours, there was just me and two boogie boarders. Anyways, all my life I have either boogie boarded or body surfed when at the beach. Then just this past January, I decided to buy me a surfboard from craigslist (6'2 20 width 2 2/3 thick) and try to "self-teach" myself to surf. Because I decided to start during the winter months here in Hawaii, obviously the waves were raging quite a bit. Luckily for me, almost every week there were waves this past winter at my break. I don't know if its because I'm lucky or just naturally athletic, but by my third or fourth session, I could paddle into waves and get shacked. For the past 4 months, thats all I've been doing, getting barreled. What I want to start doing is snaps and turns and all that other crazy xxxxx I see these guys doing on youtube.
Me= 5'11 180 pounds...my board= 6'2 20 2 2/3
-I like my board but the only problem I have with it is its thickness. The board is a little heavy and I know I should be able to duck dive deeper than what I'm doing now. What I want to know is how thick should my next board be. Any suggestions would be great.
