My Pitbull is drilled 40x5x75 (pin below middle finger) with a P3 hole as my tank since I have now dropped to 15# due to injury. I've drilled an oiler with this type of layout almost every season (HR Revenge, Ruckus Feud, Thug Unruly, Guru Supreme) and have always been happy with my results on fresh heavy oil, particularly on newer lane surfaces.
I took the Pitbull to our oiliest local house which has newer Prolane and dresses a totally unnecessary 27ml for all of their leagues. Out of the box, the Pitbull was nearly unusable for me as it tractioned the lane almost upon impact and would either not hold the line on shots inside target or bleed too much energy on shots towards the outside. The last time that I saw this much traction was WAY back with the EPX-T1. By the end of practice I had already hit it with a 3k pad to smooth out the surface and help generate length on what to every other ball in my bag looked like a heavy oil pattern. The 3k pad was perfect and gave me the look that I needed to get the ball to the breakpoint while still maintain continuation through the pins, yet I was still way inside everybody else on my pair. The best look that I've had with the Pitbull has been on fresh 45' Route 66 on brand new lanes which in this house plays extremely slick. On the fresh, most people are aiming at the middle of the 3 pin, while the strong cover of the Pitbull gives me enough traction to swing the ball to the 10 board and expect recovery back to the pocket.
The downfall of the Pitbull is that with only average ball speed and a slightly above average rev rate, I just can't use this ball effectively for more than a game or two. This ball absorbs a tremendous amount of oil and in the process obliterates an oil pattern. Personally, I enjoy playing deep inside so this works to my advantage, especially in tournament play, but it doesn't make me a great team mate to cross with in league. Although it is disappointing that I am unable to use this ball for an entire league set, it does give me the luxury of being able to get into swinging my beloved midrange favorites such as my Xeno sooner than usual.
In comparison to other balls in the Brunswick family, the Pitbull reminds me most of the Endless Nightmare as a roughed up tank that is designed for only the heaviest of oils. It is a solid step earlier than either the Guru Supreme or Ruckus Feud with a stronger midlane roll and a little less angle off of the backend. When switching from the Pitbull to my Guru LTD or Xeno, I sometimes feel like I am making a blind move as the Pitbull has me standing a good 5 boards deeper with my feet with a softer response to wet/dry than either Radical release.
The Pitbull is the strongest, earliest rolling ball that I have ever thrown and is a beast in true heavy oil. Honestly, Joe bowler on a league house pattern will not be needing a ball this strong, but for their needs there are plenty of balls on the market to satisfy that demand. The Pitbull will be a key niche piece for tournament bowlers and players with high ball speed/spinny releases looking to create roll, flare and hook on the heaviest of oils.
