The Barta Bow is a virtual copy of the Shadow, which Martin (Howatt) made in the early-mid 1990's. It was a sort of "Plain Jane" version of the Bushmaster, with laminated birch riser and black glass limbs in place of the Amazakoue riser and clear glass on the Bushmaster. The Barta grip has been refined a bit to make it more comfortable, but other than that it's the same bow.
I didn't care for the grip on the Bushmaster/Shadow (although I still have a couple). The Barta is an improvement, but of the two I prefer the Savannah.....and I LOVE my Visions!
