Drilled my Sling Blade label and this ball i found to be great on the typical house shot.  Throw it right and this ball recovered tremendously.  The Blade serious collectively tends to hook on the earlier side due to the tiny cores and flip blocks inside them.  The Big Block Diesel is one of my favorite balls in the hammer line.  Drilled mine pin 1" above fingers and out 1" cg 1/2 above thumb.  The BBD rolls incredibly true in the mid-part of the lane conserving all its energy for the backends, making a smooth roll back to the pocket for a booming hit.  One of the bigger hooking balls in the Hammer Line, but i love mine because it is really smooth roll and hits very hard.

I have not personaly thrown the Big Block but out of the box it looks like a hook monster, rolling very early with a contunios backend. Drilled 4 X 3 3/8 (the guy thowing with a simlar style). 2 1/2 inch pin.

The sling blade I do own and it does get through the lane nice and has a smoother reaction to the pocket. Drilled with pin above the bridge, and cg about an inch under the bridge. 1 1/2 pin.
