Lucas...
I don't know f any that are being made other than by Bear any longer...
Jim Gainey of Black Creek bows used to make some... I think he closed up shop...
Brandon Stahl of Rose Oak Archery used to make some, but he's no longer doing the Bear limbs... And very few bows...
Kirk Lavendar of Bigfoot bows made some for a bit... But saw not to long ago that he was closing shop as well...
So the used market may be your only source...
There are some very talented bowyers who make them... Have a friend that does, but doesn't market or sell them at the present time...
