Double reason behind this. First is that my daughter likes watching daddy bowl, and is asking when she can have a ball. So extreme lightweight is preferable, but I don't mind getting other weights for later on.
Second reason is that some friends of ours had their equipment . . . ahem . . . liberated from their house, along with some other stuff. It was a violation in more than one way, because one of the balls was her grandmother's bowling ball, and she was still using it (rather successfully I might add). She, her son, and her daughter all lost balls, shoes, and bags. I've got the bags covered, and the son throws 15#, so I've pretty much got that under control as well. But mother and daughter both throw 12# - so looking to see who has stuff at a reasonable price that they are willing to part with. Mom's a lefty, daughter's a righty, and anything from the Urethane era till today will be considered.
