I have the following used Storm balls for sale; Trauma, Trauma ER & Eraser PBT.
All balls are 14lbs, Pin Out 3", and single drill.  All are drilled right handed with thumb inserts and finger grips. The spans are approx. 4 3/4" middle finger, 4 7/8" ring finger.  The Trauma doesn't have a weight hole the other two do.  All have less than 15 games on them.  I'm asking $40 plus shipping per ball or all three for $100 plus shipping.
