What im going to say here, dont take to it 100% because im just giving an opinion based on what ive heard.
For the XXXce:
I havent thrown or know anyone who has thrown this ball. From what i hear and have read, it is got the same core as the XXcel, just a very strong reactive shell. WIth the XXcel core, this ball should have some snap in the back, but with the coverstock being very aggressive and early, this ball should read very early and have a strong midlane, and being a resin ball, it should hold up in the backends. I feel this ball will rev up very well for a low rev player like your self.
For the Hawg:
Right off the bat, the Hawg has a proven coverstock and a proven core already. THe core, previously used in the Diesel line, which by the way was a very good line, is very strong and should provide a very strong roll through out the lane. Now, the cover, which was a big hit in The Real Deal, and the Saw blade, and is now featured on the Razor Blade, Big Deal and the Hawg, is an aggressive coverstock. I can tell you from experience that the cover is great having thrown the Real Deal multiple times and owning the Saw Blade. I feel that with the particle pearl coverstock, this should have a bit more bite in the oil than the XXXcel, but being that it is a pearl, it should allow enough energy to move in the backend like a resin ball would.
My opinion, you cant loose either way. Really, here, its all a choice. ITs all about price, company preference, wheather you want particle or not. SSeeing as you have an ultimate inferno and you dont like it, there are many reasons in which that can be, but either way the XXXcel and the Hawg will both give you a different look to the Ultimate. Me, being a Hammer Head myself, i would choose the Hawg, bring as i like the coverstock on the ball (the saw blade is my every day go-to ball) and knowing that the ball;s core is proven in an entire line of balls. Nothing against the Ebonite XXXcel, i loved the XXcel, i just feel that to me going with what has already worked for me would be a good choice. So really, if you want a resin ball go with the XXXcel and if you want a little more bite go with the Hawg, but either way you choose you will not be dissapointed.
