I'm using it as thruster, tried it once as a quad - wasn't bad as a quad, but I'd have to try different fins.
Biggest improvement is to get FCS US box adaptor and putting in a equal sized set of fins - std center fin is a little too big imo - I use AM2's.
I've got a 9'0 & use the Kelly Slater K2 quad & a nubster in the center. Love this setup!
Go Zeusman.....enjoying the GL fins on the 9'10 GT....still haven't done the "sizeable wave" test but got 5 days off work so that is 5 days of surfing 
Thanks guys are the fins that come with the board any good ? Or defiantly need to change them ?
Nah they're rubbish! Definitely need to change them.
Gizzie.... Using Shapers AP2 quad & nubster in the 9'10" now... Very nice!
So which set up is better until I can get some new ones . The thruster of quad ?
These boards ie 9 and 8 5 must be among the most popular and best all round performing boards for the surf in most levels of surf out there.
I now have a 9 and 8 5 and love them but keen to know recommendations on fins so please respond as there are many of you out there.
Thanks
I'm using the Jackson Close thruster setup on my 9'5 Hokua and its great, the centre fin being smaller than the side fins makes it a bit more unstable but on the 9' 5" that's not a big issue for me though on a circa 8' board it could be an issue so try it out first IMO. 
Fcs al merricks in mine as a thruster and whack a 5" centre fin in when its over 4ft
Hi ,
I ride the hokua 9 as a thruster with the std naish wood grain sides , and a fcs 3d red tip
(standard size) in a longboard box adapter for the centre.
Have tried it as a quad with carbon stealths and it felt really bad.
I went to the naish shop in Hawaii and was told to only ride it as a thruster and that's what the shaper also said .
Now I can turn quicker , slide the tail and the 3 d gives heaps of hold in the foam when coming back down the face.
I have a lot of different fins but I don't feal any need to change, it's the perfect setup or me in knee high to overhead.
Cheers
