Right Size Dominator?

[NCounty Surf]

Hi,
I'm looking for a little help in selecting the right size dominator for me. I'm 6'1", 195 lbs, and 25 years old. I've only been surfing a few months, but the people I surf with say I look like someone who has surfed for over a year and categorize me as an intermediate surfer. I have no problems catching waves or taking off late, I can move down the line, turn, make cutbacks, and make my way around closed out sections of a wave. I'm currently riding a poly fish measuring 6'8"x23x3 and I'm looking at the 6'6" and 6'4" dominator. I'm want something shorter with more curve in the tail to free up the board so I chose the dominator. Also, I'm lucky enough to be able to surf 5 days a week so I would like something that will help me to continue to progress and still be fun in small mushy conditions. Any tips or advice would be greatly appreciated.

Thanks
