What is an ideal board for 6-10' San Diego reef waves (slow)

Hello,
So I'm not that experienced. I've been surfing a little over 4 years and I ride a 6' x 21.75" x 2.6" board. The board was custom shaped by Robin Pradonovich and is pretty round. It's a slightly modified take off of this board

So I took that out in the recent swell and basically just floated around and fought currents the whole time. When it gets bigger, I often find it harder to get into waves at all. I can paddle and basically catch them, but right as I'm about to drop, I'm looking over this steep face and I almost always pull out. Part of that is that I think I need to have bigger balls, but also this last time it felt like I might have done better on a longer board, like a 7'6" or something.
Keep in mind I'm talking about the reef waves of San Diego. Big, fat and slow. I almost never surf the beaches when it gets over 6' because 1) they are too heavy, and 2) most are closed out, except Black's of course, but I'm not ready for that on a 6 foot+ day.
So this brings me to my question, what board should I be riding for those waves? I was thinking a standard performance egg at 7'6" x 22" x 2.75" would probably work or is that too wide?
