Hope the surgery goes well and you have a speedy recovery, tmiller. I've known two people who have had that procedure in less than a year, both of them the bowling arm. The first is bowling already and definitely getting back in form, as his was last June I think. He was going to the lanes and doing a
game or two in late September and came in a filled in an open spot on one of my teams my mid October. This was on top of a broken ankle in April/May from a motorcycle accident. He was bowling once his ankle was in a walking cast and could support some weight to balance himself, he just had no approach. The other guy just had his surgery so his season is over.
As for the
balls you have for sell, they are a pound heavier than what I use so I can't help you there.
