Symmetric drillings for V2 clean.
http://www.ebonite.com/techcenter/drilling_instructions.php?title=Symmetric%20Core#1 = label leverage, lots of flare less midlane then stacked leverage.
#2 = Standard stacked leverage
#3 is one version of revs leverage another version is the pin is equal distance ABOVE grip center line as the cg is below it. This version has pin equal in the north south direction to the grip center(more likely than the version I detailed to track over fingers). I've used this drilling on heavy head oil with great success on reactives only! Just REVS earlier!
#5 = label, just less of everything than # 2 but similar shaped move!!!
A whole class of important drillings is missing and these would be cg kicked out or control drillings. Which supply a hook set effect or hook roll type of reaction. A drilling like this would be listed as 4 X 2 or 3 3/8 X 2 with a weighthole on PAP. These numbers designate pin to PAP distance X cg to pap.

PS I was going to go to Lane#1s drill sheets which are fantastic also but my browser(no longer internet explorer) was not compatible with their site!
My loss!
