I have taken this board out a few times now and each time just gets better and better I thought it would be a struggle at my weight of 105kg but its actually pretty stable.
It absolutely rips on a wave and in good surf it comes alive I'm sure it makes my surfing better than it actually is...
Today I took it out the bay in 0.5-1 foot peelers I wasn't expecting much thinking I should have brought a bigger board but I caught lots of waves some long rides with fun turns even on my backhand.
Even on flat water it glides nicely for it's size. I still fall off a bit in chop but after dialled in I can see it's gona be a keeper.
Only used shapers quad fins so far
I got mine about a month ago. I love it. The board is much more stable as a quad. I'm using the PC7.
I have recently acquired one myself and at 83 kg i find it quite a gravitational challenge yet not impossible.
I cant imagine i could even float on it at 105 kg!, define "pretty stable" 
They do surf exceptionally well though when you manage to stay upright and get on a wave. 
Maybe i need to get the quad set up going.
Quads are the only way to go large in the front( I'm using Mark Richards twins) & small in the back 
I just realised i have three FCS fins on my old Aloha so im giving the quad a crack, only thing is the fins are about the same size as the the matching two from Naish.
.......How would 5 fins work. 
So figuring I really need two bigger fins what size should i be looking for to add to the original two that come with the thruster set up?
Also do you think having the large single fin further forward as a thruster setup would be more or less stable?
Actually i just found this old thread, www.seabreeze.com.au/forums/Stand-Up-Paddle/SUP/Fins-for-surfing/
Normally you could leave the factory fins & go with smaller fins at the rear. Check out the the fcs website.
I don't think the centre fin position will have too much effect on stability - more influence on turning ability.
Quad fins move surface area closer to the rails - more stability
OK, thanks for that, im going to try the quad fin set up with the two Naish at the back and the ones off my surfboard at the front and see how that goes. 
I will report back tomorrow, should be nice surf again as it was today.
Easy now some of us have to work... Hope the quad serves u well let us know
OK, so i went out at a nice 3 foot sand/reef left hander and on my first wave i went to bottom turn and fell off, LOL, so it certainly has a different feel over the thruster setup, i didn't really notice too much difference on the stability.
It was still hard work the whole time, i will have to do some more tests to work this out, tomorrow. It was definitely a looser setup though once on the wave.
Well today i snapped my leggy so didn't get in a long session, but it was windier and the board is still very tippy IMHO, to be honest i don't think i can tell the difference between the setup i have and the thruster, though having two larger front side fins would more than likely be a good idea in my case and i think that would improve things a bit.
Of course the two fins Ive added are totally different from the wooden Naish ones so its no surprise the whole thing might not be the best setup imaginable. ATM i have the plastic fins up front and the Naish wooden ones at the back, maybe i should swap them around?
I do though like how the board keeps a high line on waves and is noticeably faster as well so im going to keep with the quad setup as i like the feel of it on a wave.
Back to the salt mines.......... more testing tomorrow.
Picked a good time to do all ya testing... So jealous.
I'd buy a decent quad set if u can and see if that makes the difference it will be a good investment anyway I'm no fin expert but that setup looks a bit stocky and not the best...
Keep trying on the board honestly my balance sux big time and I find it ok.
Where r u surfing?
Thanks for the advice, i will look into that i think, getting a full set of quads.
I'm out and about on the central coast, its been particularly good at spot X, Y and Z lately
.....I don't want to upset any locals.
I didn't get those wooden side fins with my 9 5 Hokua.
Im experimenting with quads right now.
Running GL front and FCS g 1000 rear.
I like how loose and quick the board feels with this setup.
But I do think it makes it a tad more skatey, and therefore less stable underfoot while negotiating for a wave.
Im near 100kg and have found the board stable enough and a good performer for my skill level (intermediate and rising.)
I do find in steep waves the board threatens to nose dive often (little more rocker needed perhaps)
I have a 5th fin / nubster in house and will begin to add that to the mix
I thought your white ones looked the same as mine, but mine are called m5 (from 2006). It looks to me that your front fins are a bit bigger than the rears.
Skatey is a good description IMO, i find it hard to catch waves backside but am fine going forehand, but it could well be that im just crap.
OK, i looked at the FCS site and see your back fins are very small, I cant find your front ones on there ATM, i really need to get the bigger fronts/smaller backs setup i think and see how that goes.
Ah, you have the Gerry Lopez (GL), any reason you dont use the GL rears?
The GL Fronts are noticeably bigger (moreso than my picture indicates.)
Im still in the early experimentation phase, but I like the larger GL upfront, and I wanted something even smaller than the GL rears. The GL rears have more depth and more area than these G1000'S. I don't know how this compares to your wooden Hokua sides, but I would definitely suggest you try the larger fronts, smaller rear quad setup.
