I have two 14lb balls that have very little use on them.  The span is approx 4 1/4"; both have finger inserts and a thumb slug.

XXX Factor: pin under ring finger; cg kicked out to the right slightly; small weighthole; RAD between thumb and weighthole; 2" pin out.  About 10 games bowled on wood surface.  $70 plus actual shipping.

Sling Blade: pin above and between fingers; cg kicked out slightly; 3" pin out.  About 10 games bowled on wood surface.  $40 plus actual shipping.

Take care....JS
