I have a solid 15# cobalt, super carbide bomb and pink panther for sale.  Cobalt has a couple of small scratches in it, panthers cover is mint, super carbide bomb is very good.  I haven't bowled in at least 3 years and they are sitting in the bag in the closet.  Both balls drilled right handed (single drill), approximately 4 1/2 cut to cut.  All have weight hole in the lower right quadrant.  All are  $75 each plus shipping.  Pictures are available upon request.  Leave a message here, or at my email, sgl1956@hotmail.com.  Sorry no paypal or credit cards.
