I think the idea is that the extra lams don't really start to come into their own until the weight becomes a factor. For the guys ordering 70# and up from Hill, the extra lam probably does feel a bit smoother. There's a point at which the extra lam and the extra glue line are kind of a wash. My building, pitiful though it might be, seems to bear this out. I build a series of 1, 2, 3 and 4 lam bows for comparison. Came to the conclusion that at my low weights, I could probably build everything with 2 lams, but I generally use three "just because" or to get a color contrast lam in the middle (very scientific here). If I'm aiming for 45 or more, I got to four.
