Like Steve was saying there are other ways to skin the same cat besides using a lot of thin lamination's too. Carbon is one of them, and using action wood Lamentations is another. i find that using action wood on recurve limbs which are wider and thinner really helps out a lot.... but it also works very well in long bow limbs too.
looking at the side profile it only looks like 2 or 3 lamination's in the limb, but what you don't see is the 7 vertically laminated pieces in the core of the limb.
Here is an example of the action wood i lay up myself from rock hard maple & some i've mixed with walnut strips too.
