Hey, i hope i might be of some help
I have a Sling Blade drilled like this..

On a Medium, fresh pattern, this ball shines VERY WELL. My specs are in my profile. I'm a tweener with a little extra revs, if that makes since, lol. I throw about 16-18mph, just depends on the conditions.
For me my Sling Blade, has a very sharp backend with this layout, but at the same time, is still controllable. The ball revs up very nicely, and gets down the lane easily. I can play almost any line with this ball.
Overall the Sling Blade really shines on Medium Conditions. On Lighter Oil, it might get tough, but you will find a shot eventually. On Dry conditions, ahhh, put the ball back, lol
