Mike, this one is just to see diff in glass between the two. I've heard from heavier to 5# lighter...
I'm thinkin each set of lams may be different even from the same board, you might get more pressure at glue up for a thinner glue line, and different width on limbs by a few thou could all change the outcome.
I'm just finding out if there is any glaring difference.
When I try the SK, I will reduce stack by .016 since it's sposed to be stiff!
