7'8" or 8'4"??

Hey guys,
Another (very) beginner surfer here, I'm from New Zealand, and I'm looking at getting a first board. I've been into a couple of shops and talked to the guys there about what kind of board I should be looking at. They've recommended anything from mini mals, to super fishes and a 7'9" short type board. Doing a lot of research, and I know I need, ideally a mini mal. Have been hiring boards from a surf school to get out amongst it. The one I've been hiring is a bic 8'4" mini mal. Which seems to be a common board as a first step, and have thought seriously about getting one. My question is, I've also seen a mal for sale at a well known New Zealand shapers website, Barron surfboards. It's only $100 dollars more than the bic. And would prefer it over owning a pop out. It's 7'8" 22" wide and 3" thick. Versus the bic at 8'4" 23.25" wide and 3.20" thick. I'm 5'10" and 80kg, very beginner, but can stand no probs on the bic. Would I notice much difference between them? Thoughts?
Cheers guys
