Gday. I bought a 7'3" 7S 2nd hand as an experiment in getting off the longboard. It's set up as a quad with M7s and GXs but with one GX missing. Should I buy another GX or would it be ok with the little GL side biters from my longboard in the back instead, keeping the M7s in the front?

I have no idea about fins, but Im 43, 81kg, nearly average ability who's a bit front footed, generally surfing 2-3 foot below-average quality waves, if that helps.

Thanks.

Set it up as a quad, M7s or M5s and yea go the GXs in the back..

G'day,

I have the same board... and at 81kg there will be no problem with you catching waves - I'm nearly 30kg heavier and go OK.

Def. set it up as a quad - as it will be faster and loser than a thruster... however I would think that the GL's are likely to be too small in some situations.

You can always just try them...

I have the Simon Anderson FCS S25 core flex in large (fibre glass with a 'honey comb' type core) and reckon they are great. They will transfer over to any new board.

save me starting another thread.. but i wanna try my board as a quad.. i was given 3 x m5's and 2 x m3's with the board.. use the m5's as a thruster at the moment

probably silly question.. but m5's on the outside and m3's on the inside for quad setup yea?

Whatever - so long as the rear pair of fins are slightly smaller than the front pair (or at worst, the same size).

thanks guys Ill grab another GX then and see how it goes.
