Just a question, before I ask Hammer (who have a nice customer service): does anyone know for sure what the black Pure Hammer's coverstock material is? I thought it was solid urethane, but the box said to my surprise "reactive" and I am stunned how strong this ball is on the lanes (IMHO much too much for the "light conditions it was advertised for - it is smooth, but VERY powerful, even though polished and drilled weak/for length).

If any Hammer affiliate has a clue, please share it with me. Thanks a lot in advance.

I do not "know", but have read many times that this coverstock was a reactive/urethane blend. The cover is medium; so that could relate to the ball's apparent strength. A friend used one 2 years ago and the more he polished it, the harder it hooked. It's still a light to medium-light oil ball.

Of course, "light" is a very relative term.

If you want to use it for lighter oil, try a weaker pin position and less added polish.

I got mine NIB, last of its kind in the pro shop. I knew that it would be stronger than expected (Some bowlers who owned/own one cursed it, too, for its strength), and to give it length we polihed it before drilling.
Pin is set very high, 1 1/2" above the bridge and the CG is stacked in the palm area (it has 3" pin). On dry lanes, it hooks like a monster (more of an arc, not flippy at all). When the lane is fresh with medium oil, it slips... very strange. Best condition seems to be e light, long pattern, and I thought about scuffing it back to 1.500 grit, just to see what happens. Strange ball. Carry is great, it is nice to control, it just moves way too much...

That is a relatively condition specific drill. and the polish makes it more so.
Small womder then, that it "slips" on medium oil.

If I might suggest, without re-drilling try to take the coverstock to 2000 grit (now made famous by Abralon); that will provide length and reduce backend and make it less susceptible, IN GENERAL, to over/under on heavier (read: medium) oil.

I've been thinking myself recently about the Pure Burgundy (only because that is the one that is now available). If I were to drill it, I wouldn't place the pin so high (but a lot of that depends on what the "up" or height portion of the PAP's specification was. Mine is 0 up/down). I'd place the pin below the center of the bridge around the 5" pin-PAP range (maybe even 4.5") and kick the CG/MB out a little) - producing about a 5"x4" drill.

I'd be inclined to use it a light to medium-light control ball. Not necessarily a light oil ball. A friend drilled one with pin on PAP and now his is a VERY condition specific ball.

I was told by my pro shop guy that the black pure has a very small  amount of resin compared to normal resin reactive balls.

I had one drilled with the pin 5" from pap and the cg in grip center.  This ball was also polished.  I was able to use it on dry lanes.  It reacted very smooth.

I wish I had another one of these balls.

It is a blended reactive cover and fairly strong versus its itent. However, it does perfrom well, has a highly tunable cover and can work for second shift, light and/or short conditions. Mine is drilled pin within 1 1/2" to PAP because I wanted it for drier conditions. Unlike chitown, mine is at 1000 grit matte. The one thing, which I got straight from Brian Graham at Hammer, was that you have to let the ball soak up some oil to mellow the reaction or you'll think it's too strong. He was absolutely right.

Thanks a lot for your replies and suggestions, you are a great help!

Originally, I asked my driller to set it up for drier lanes, and since I have a Sahara with the pin above the ring finger and MB stacked, he decided to put the pin that high for ultimate length and a smooth turn. He knows his trade, and he knows the ball from other bowlers.

The turn IS smooth, but after some weeks' testing I got the impression that the condition window in which the ball works for me with its current surface is very small. It might be my style? I can hardly blame the ball for its movement

Astonishingly, the ball does not burn out on dry lanes, even when it moves so much, so it works correctly. The coverstocks also "feels" mild. It just moves sooo much... maybe I'll try either a high grit surface to tame it down a bit, or consider a balance hole (even though it does not flare, maybe 1" at all).
