I've only been surfing for about 5-6 years. I know there are plenty of older surfers on this forum who have a lot more experience then me. So.. I figured I'd ask on here about my own quiver.. which I seem to be having trouble understanding.

It seems like whenever there are waves only about 50% of the time do I feel like I have the correct board out (out of my 3 choices).. I want to know more about the boards I have, like for example if they are to thick or to thin for me - if I should ONLY be using this board in this kind of surf, or certain ways I should be using the board, etc.. the 3 boards I have are as follows..

5'5 custom, 19 1/4 x 2 3/8 (quad) - (This was ment to be a competition kind of groverler board but still have performance aspects. I really love this board, but I feel like its thickness takes away from its performance especially since im only 125 pounds. I also have yet to even get it airborne, which is probably just my skill level and nothing to do with the board but i'm having trouble understanding it. Low entry rocker.)

5'6 custom Stealth Pro (Lost) , x 17.88 x 2.13 (tri) - (Lightly glassed from Matt Biolos, this board was really ment to be a good comp board but I feel like its to thin and getting into waves seems pretty difficult. Should I only be using this on big days? Should I have gone thicker?)

5'4 CI pod, x 19 1/2 x 2 1/4 - (Just a fun board, the pod is the pod.)

My height and weight is as follows,
Height: 5'6 1/2
Weight: 125 pounds

My question is pretty much.. what should a board for me look like? Should it be that thick? Or should it be that thin?

I just want to know more about my quiver, and know when to use what boards. Like for example if we get waves on sunday, I really don't know what board I should be using at that time.

Thanks for your time.
