The Katana Slash is a terrific option if you're looking for a versatile ball for a variety of lane conditions. If you don't have the budget for a 6-9 ball arsenal then certainly this is a must have option. Mine is drilled 55 x 5 3/8 x 45 and I see easy length, a clean shape, and really strong hitting power. The Katana line continues to excel with a great complement to the original.
This ball takes really well to surface adjustments, I don't have a great deal of ball speed but have been able to use it on patterns as short at 36' and as long as 44', truly this is a winner.
Tom Smallwood ran the table and won the PBA Players Championship with this ball, take a look at it online just to see the potential.
A great option for any serious or semi-serious bowler.
