I have one S/L sled, it has a power lam built in the butt end of a .001 taper and a tip wedge on the other end, both about 11" long. Some of the tip wedge cuts off with the lam cut off at tip, and you can cut a little off the butt end to move the bend toward riser if needed...

The power lam would be in 2 pcs unless you skive joined it . The bows I originally made it for were one pc with the belly lams running up the riser ramps and stopping a bit from center of bow.
