Here's some info on a wood strip board I just finished: 137x43, 33cm tips, 4cm rocker, 3mm concave, 38mm rocker.
The goal is to be all-around board for 80kg rider in area where lulls come more often than gusts, with some tip area and width for both pop and glide, but not too flat a rocker line... ...hopefully the rocker, tapered tips and light glass will keep the width from causing too much of a beating when it blows up and gets choppier... Tips seem maybe too flexy, but the middle is fairly stiff...
A few details....
Core 2 layers of ~7mmx20mm western red cedar strips
3mm thick at tips, ~14.5mm at center, ~6mm at rails
Rails and inserts are epoxy filled with cotton fibers and graphite
Rails rounded 50/50 between straps, harder at tips
Skin 6oz e glass plus 6 oz eglass reinforcements
Resin Research epoxy.
bare 3.2 kg
The weight has me wondering if I should have used lighter straps than the luxuries, which add more weight than I like - they are like 500g apiece but nice and soft...
The strips I started with weren't milled precisely, and I had no planer, so there's a bit more epoxy in the core than I wanted...
Easy to get shape right with 2 layer core, but a single layer would probably save 150-200g. Maybe next time, this one was partly just to use up the strips on hand....
Not ridden yet, we'll see.

Just wanted to post this board to say thanks to those who have given some advice along the way, it's the first one I have made for a while, I'll try to give an update on how it rides, when I get around to riding it....
