Sizes are 141x41, 134x39 and 131x37.
All are 1/4" birch doubled for the core.
1 - 3.7 ounce fiberglass hand laid top and bottom (the pink boards I did two layers of fiberglass)
Stainless Steel inserts
All have quite a bit of concave.
One thing I discovered is there is a major difference in the quality of wood you can purchase. The first two boards I built I just bought the $15 4x8x 1/4" birch from menards. The first board snapped right under the footstrap after about 3/4 of a season. The second board is the Reign pictured here and I am hoping it doesn't snap. I built the other boards from the $30 dollar version, which if you look at the sides of these sheets there is a real difference. The good wood has 5 solid layers, where the cheap stuff looks like 2 of the layers are real nasty looking.
The Reign does a good job in the chop and has a lot of flex. I did change the next boards rocker line because this one has a symetrical rocker line and the tips don't flare up and sometimes I can bury the front of the board if I ride it too flat.
The Zion is probably the best board I built and rides great in flat and in the chop. The rocker that I changed is more of a 3 stage where towards the tips the rocker line flares up more. This made a huge difference in the tip not getting buried and not catching a edge in the chop.
The Divine (wife's board) has more of a skate feel and doesn't have near the flex of the others because of the double layered fiberglass. I did the double layer on this one after my first board snapped. This is also the fastest of the boards.
Hopefully some of you can use some of this info and save yourself some time and money. Fire away with any questions.
