I can honestly say ive never seen an ipe, unbacked bow.
By the way, congrats on the bun in the oven.

I see IPE sets a fair amount "
Usually, IPE has very little set. I can only assume the light weight of this bow, plus the touchness of ipe with out a backing, is what created the set. I get very little set at all with Ipe. I love the stuff for that reason. Plus the density. You can make thin bows with ipe due to its density.
