I have too many bowling balls and really don't have much use for 3.5 even though my personal best series came using this ball in the only set I threw using it. It has 5-6 total games and not a mark on it.

C-(System) 3.5
Weight: 15lbs
Pin: 3"
Span: a tad over 5" full grip
Vise IT installed (will not come with the slug)
X-Hole: yes
Price: $70 shipped
