Because there are so many fins about and they are not a cheap gamble....well post up what you got,or what you want or ask Lacey on what he thinks.

I'm going to pick up a 9" one of these bad boy's on Friday....anyone used something similar?

Its a definite trend with high performance longboards these days not to have a finbox - just a 3 fin plug setup.
This is a pic of the Harley Ingleby "world title" model shaped by Billy Tolhurst that we just got in. And its a triple stringer to boot, cos you're gonna need some extra strength wielding that baby around like big shorty!
Steve Del Rosso at Clearwater is mostly doing this type of setup too on his performance boards, as is Tully St John up at Laguna Bay longboards.
I rode Mark McNamara's and Clint Guest's finbox-less Clearwaters recently and what really surprised me was how relatively stable they were on the nose, given the lack of fin volume/hold compared to what I would normally have on my fin-box longboard. Its made me re-think my whole setup. Damn it!
Anyway, plenty of Pro's and Cons here. Definitely not for logging though. What are you thoughts? - Mark

?

I think so - would be a great complement for the days when you don't quite want to battle a 9' board but dont' want to ride a shortie

Here's a board I picked up yesterday. Cant wait to jump on it. I got a box to ride it as a single as well. its 7'6 x 22 x 3 double ender.
