Due to very dry conditions I'm looking into getting a urethane ball and am considering the Blue Hammer or the Storm Super Natural.  How do these balls compare?  Would the Storm have a little more snap than the Hammer? 

Thanks for the help.

I suspect thedjs is talking about the current Blue Hammer.
I've had both, the SuperNatural and the new Blue Hammer. The Blue Hammer is a solid urethane/resin blend and comes 4000 grit matte, while the SN is also a urethane/resin blend, but is a solid/pearl combo and comes highly polished.

I found the SN to be very susceptible to the vagaries of oil even when the lanes appeared very dry. You had to hit a lot of very dry to insure it would hook.  Of course "very dry" and "a lot" are very relative terms; I can't say you and I would think of them the same way.

In any case, I found the new Blue Hammer to be more consistent and to have some excellent and surprising hitting power.  (While even with such a ball I rarely am able to play down and in, one time I was playing about 10 out to 5 in a practice session, I hit the pocket a little light and threw the head pin against the left wall; it ricocheted across the lane in front of the 10 pin and would up back around the 5 pin spot. Now I rarely do that with resin balls, so I was kind of surprised to see that happen with a urethane/resin blend intended for very light oil.)

I sold the SuperNatural and kept the Blue Hammer.

Thanks for the help.  I think the Blue Hammer may be what I'm looking for.

Havent thrown the Super Natural, but the new Blue Hammer has been great for me.  Had a good look with it on the Wolf pattern, and shot 2163 for 9 on a house shot tournament.  I disagree that urethane is only for short patterns.  It can be a great option on the wet dry house shots.  Especially good for strokers who can sometimes go straighter outside ten, rather than being forced to go away from the pocket too much with a more aggressive resin ball. 

I drilled a Natural Pearl last week. I have not thrown it much, but it does not roll like most urethanes. Last week I was able to get on top of the dry during the third game and the ball did not  roll early like you would expect. It picked up some and the middle and made a sharp hard arc in the back of the pattern. Carry was better than I expected. I actually rang a couple of tens. No flat hits.

No way I could do that with the Natural. It would hook and roll early, arcing to the pocket. I would say that the ball has good potential from what I am seeing. You may want to consider it.

It is hard to say how the new urethanes compare to the old ones, because oils have changed so much, and patterns are much longer than during the hay day of urethane in the 80's.  My guess is the formula has been tweaked, and the cores are stronger.  If you actually encountered a low volume 24 foot pattern from the 80's these new urethanes would probably be much stronger than the old ones.  As noted, most people used a lot of surface on those old balls.  The original blue hammer came at 400 grit from the factory.  The ball didn't really maintain that surface for very long, and it soaked up more oil than people realized at the time.
