Thoughts on this fin set up?

As some of you know about a year ago I was trying to work with a 6’0" quad set up where the fins were way to close and I don’t think the fin placement was optimal. I ended up getting a set of keels from Larry at Probox and altered them to fit my FCS plugs. The set up works really well in really small surf but when it gets a bit bigger I would like some additonal bite.

What do you guys think if adding a small C5 fin in the 2 rear single plugs to add some hold? Here are a few pics (hopefully I can get this to load from my phone?

the rears are single tab small fins with no CANT to them as you can tell from the pictures they are straight up and down. Sorry for the sad pics, hopefully you get an idea.

Usually the rears are straighter anyway, so the fact that they have no cant could be OK…

Looks like a fun experiement. Go ride it and post a report!
