Okay so the lack of surf (for me

) has me looking at boards again..
The last few times I've been in the drink its been with my kids on very small days. I have my board in tow, and even pulled out my 6'6" fish but to no real advantage.
SO my question is Sweet Potato

Good bad and will it work on days when its super small?
I have seen demos but i struggle with time to do that. Will probably buy and if don't like it sell it.
Im 90 kilos or just under, 5'8" ish and intermediate surfer at best

Any size suggestions? And to help save my marriage any second hand around
