I like it as a quad to about shoulder, but beyond that I ride it as a tri. Actually, the fins I use as a tri are more of a twin plus trailer setup, but with regular tri fin spacing. Works well to a few foot overhead. Beyond that, that size the outline of the board becomes an issue, as does the outline of my belly and general out of shape condition.
That said, I like having the 5 fin option, and am glad I got it. My shaper charged extra. My last board is a really short stubby small wave board, ad I didnt bother getting a center fin since I didnt plan on using it beyond chest high.
Similarly, if I ordered a bigger wave board, I would probably go with a tri setup, because in biger waves it feels right to me.
I suppose its a lot of personal preference. Ive bever tried a true 5 fin, but have seen some positive reviews of Griffen 5 fin setups. Ive also never tried a mckee quad setup, but that is supposed to work well in big waves. Theres some old school footge of curren riding big J bay on that setup decades ago.
There is so much to fin placement, size shape etc, it hard for me to really grasp. When i get a combo that works, I tend to stick with it.
For quad I currently use mr tfx fins up front and 2 double foil gx trailers in the rear.
For tri I often use the mr tfx and one gx or the smaller mr trailernin rear. Sometimes some AM fins front with a really ol gx3000 rear.
All my boards are round tails and I am just over 200 lbs so I use more fin than the average sized guy on a shortboard.
well its a nubster, so no worries but i tried all different types of fins etc
the only shaper i know of doing the former is greg griffen in hawaii. most are doing latter.

Kelly's knub fin is slightly behind the rear most twins, which makes sense.
ot - I just got hold of a rainbow knub I'm gonna try as the center fin on my tri. I've been using a smaller GS trailer fin in the middle on everything up to head high and it's been working just as good as a full size fin, but I'm always on the lookout for less drag on smaller waves (while still being able to dig into a bottom turn without sliding out)
EDIT: ^scratch that. I have the old "H" style FCS fin plugs (not Fusion) on my tri and realized using a fin with only one tab could easily damage or bust out the plug. On a quad, there'd be some protection from the force of water by the rear twins...plus, the FCS knub is smaller than rainbow.
