The riser is Bacote.
And yeah, They feel different. The Robin Hood is only 55#. This bow is 100#.
I love the Robin Hood bow. Mine is dual shelf and is soooooo smooth. I love it.
My Elephant Bow is super smooth, too. But, if you are not used to the hand shock that thing generates it will rattle your teeth.
Here are a couple pictures of my Howard Hill Dual Shelf Robin Hood.
