I'm not sure if "Block Drill" is the right name, but I had a Rising SE drilled this way a few years back by a proshop owner who suggested I try it.  This ball with this drilling has a consistent strong backend on a wide range of conditions but it is never jumpy and I wanted to know more about this layout because it is effective and not fussy.  There is one other high rev cranker I know who has almost all his equipment drilled this way.

When I've shown this layout to some very experienced ball drillers they really racked their eyebrows up to their hairline and muttered things like "this is one weird drilling."

I am a stroker with moderate to medium revs - PAP is 4" level, not up or down - a higher "3/4" track.

This layout puts the CG in the fingers, a weight hole directly above the fingers, and then the Pin another 2 to 3" or so above the weight hole - all three in a line through the center of the grip.

Anyone familiar with this drill and know more about when it should or shouldn't be used?
   

Only time I say anything close was years ago when some drillers were trying to take only finger weight out, and of course, back then the pin did not mean much.

By the way, with a 4 inch PAP, you track can not be that high.  You should probably have your specs checked again.

it is a puzzlement, because I own an embarrassing number of balls - cover most of a garage wall, with a variety of conventional drilling layouts - but I often end up using this Rising SE with this odd layout, simply because the reaction is so strong and so reliable on about any THC/Medium to Wet condition.

And this Rising had a very conventional layout, I think 4-1/2 just above the fingers, before I plugged and redrilled the current layout.  With the earlier conventional layout it was just another ball, and now with this odd layout it is my go to ball.
