I do not use more than 350g for a finished product.
Rekon theres some misunderstanding/language barrier going on cos ^^ that just ain't possible unless your using f*** all glass.
Nope, I am using a bamboo (doesn't drink epoxy at all), which has got only 2x200g biax FG (or 180g sometimes) and a corecell top layer with carbon. Plus a PU rails.
As you see here:

For the top FG and gluing a top layer, I've used only 62g epoxy. For the carbon and corecell layer I've used 52g 5:1.
For the bottom FG and a topsheet this is the 207 epoxy mixture from my diary:
21(A)+6(B), 14+4, 21+6 (remember, 207 is 3.5 by weight)....
which is 72 grams.
I never ever calculate any FG-epoxy ratios, if I need more, I mix more as seen on the above examples:) 207 is slow anyway...
Than it goes epoxy finish before varnish, which is: 7+2, 10.5+3 (next day) + a few more...
Makes it way below 350g...I can do a diary for my next one as always.
So, yeah, I'm quite happy with my epoxy usage. Enviro friendly boards:) With the SuperSap from Entropy that would be even more environmentally friendly.
My current board has got 200+ hours on the water, almost 2 years young
