This may be the ball I've been looking for. I've been either looking for an aggressive hard driving solid reactive to replace a very worn out Vortex 2 or a solid particle to replace a very worn out Adrenaline. This ball says it's going to be made for heavy to medium oil. It's a two piece ball, which I like better anyways and this "Reactor" coverstock was made on the Screamin Banchee which I also may be interested in but this ball is supposed to be a little more aggressive. I want something to compliment my Eraser Particle Pearl. I don't think I'm interested in a Vertigo or XXX. I don't need a high priced 3 peice ball that's unversitle. Plus my rev rate may be too high on most conditions for those anyways.
I've seen the Screamin Banshee and it looks pretty good but this Diablo also looks good. This ball can be seen at http://www.buddiesproshop.com if you haven't seen it yet.

For me personally I would recommend an Atomic Charge with a stacked leverage drilling with the pin under the ring finger.  Keep it dull and this ball will be able to tackle heavy oil.  Its a very good ball that hits like a ton of bricks.  I don't think it got the recognition it did.  If you want something even stronger, go with the Fired Up.  All I can say is WOW.  I drilled on for my friend and actually wish I drilled it a little weaker now.  That new Reactor resin is really strong and the core is strong too.  I tend to agree with Pat that the XXX and the Vertigo are very versitile.  I have a XXX with I keep shined up for when I need length and it works great for me as a control ball.  Thats what I would recommend.
