buying a new board soon, Please help.

Hey! so what would the best dimensions for a surfer in southern california (San Diego)!? Im 5'8" 160 pounds 17 years old that has been surfing for about a year a 2 months now. I use to ride a foam Wavestorm and I now currently ride a 6'10" with a quad set up and a squash tail (I don't know my exact dimensions on board; I had bought my board while I was very excited to just get riding on a different board. so, ultimately it wasn't my best decision when i bought it but oh well aka kook haha) I don't know what to consider myself as a surfer but if I had to choose i'd say i'm an advanced level of a beginner surfer or beginner of a intermediate surfer haha I dont know i'm just saying.
Factors to consider i guess:
My paddling is better than avg because I was a water polo player for 2 years
Times i surf per week currently: 0-3 per week (0, has been happening lately in past two months.)
waves i can surf: shin - chest high (couple shoulder waves. I think?)
The car i have now is a Nissan Sentra
My current board is thick & wide. so yes theres a lot of float to my board so sizing down will be somewhat difficult if i get a lot less volume
more of a rocker on nose of board
I'd like something with more volume
I don't paddle out when its really big. (yet)
SAN DIEGO BEACHES GET CROWDED
beaches i mainly surf just in case you guys wanted to consider this as a factor:
Imperial Beach
Tourmaline
Scripps
Ocean Beach
Sunset Cliffs
Hope to hear from you guys, sorry for all that info.
