For Spliced lams (walnut/maple) with a Bamboo core I'm trying to hit a really light weight (around 30#). I planned to put my Bamboo on the back but I've also seen it on the belly (both on 40# bow's). Is there a reason one would use the belly or is one better than the other? for this weight range would there be a preference?
Thanks Gentlemen

Is this an all wood bow or is everything under glass?

Maple has better properties for compression so most put it on the belly.

Lots of high end recurves have a boo back and maple belly.

2X this statement..... 

On ultra light draw weights, building recurve limbs and even hybrid long bows with decent stability can be challenging depending on your design.
Taper rates and limb thickness will affect torsional stability a lot just using glass backing. Using a par or even a reverse taper on RC limbs to thicken up the limbs at the base of the curl makes a huge difference. But aggressive hooks and static tip designs are much better with a bias weave carbon back.     Kirk

I was going to use Bamboo but after checking widths I'm going to have to use Maple for this build. So it sounds like Maple on the belly under my veneer is going to be the best route to go from what is suggested. I appreciate the input fellows. Thanks!
