Have a faithful black ops drilled weakish, 5 1/2x 5x3. I keep it at 1000 and use it for my heavy oil, volume ball. Had good success with it at nationals, bj’s in Syracuse. Well it has a ton of games now. Was thinking of putting it on my spinner and resurfacing it to oob finish and using it for mediums,  and house shot. Want to get a new, fresh black ops (great deals online for black ops around $100). Was thinking of going a little stronger with the drilling, say 4x4x2 with same 1000 surface for heavy oil just like current one. Do you think it will be too strong, I definitely don’t want it to puke out. What are your experiences with the ops, break core with strong drilling’s for oil? Here are my specs! Pap 5 3/8 over up 7/8. Tilt 16 degrees. Rev rate 320. Ball speed 14 mph. These specs are from the powerhouse bowler I’d test. Appreciate your global 900 expert opinion.

Love my iq tour also. Black ops with surface will be a similar smooth motion to the iq tour, only stronger overall. Least that’s what it is for me, and my game.

@Doom, I have a Black Ops that I love drilled at 46*4 1/4*60 and I have a Covert Ops NIB that I was thinking of drilling up. Would you recommend using the same layout or not? If not what would you go with? PAP is 5 1/4 right and 1 1/8 up

I would try 70*5*30 for a different look personally!

thank you sir! I will try this out!

What surface do you keep the Black at and what kind of motion are you looking for?

I typically bowl on a house shot in league. My BO has a out of box finish (not sure how to change the surface).

Personally, I like the layout on the Black in the Covert, just keep the Covert at 2000 (see your pro shop for proper cover maintenance) and use it when they're fresh, then step in and use the Black when the Covert starts to leave corners.

Thanks Doom. I will talk to my pro shop.
