I think it's fair game to put the question out there. While bowling in an eliminator last weekend, a local pro shop proprietor who has bowled out there nationally and regionally posed some interesting facts to me. Like you TKK, he mentioned aside from Sean Rash, who else do we see making shows? Thomas Smallwood, Jason Sterner, Ryan Ciminelli, and Tom Hess? And out on the PBA 50 circuit, WRW, Parker Bohn and John Petraglia?
He believed Brunswick's coverstocks have been inferior to the likes of Storm/Roto Grip and Motiv in recent years. He maintains equipment alone at that level of competition is worth 10-15 pins. That's the difference between cashing and not cashing. Making shows and not making shows.
Personally, Brunswick and its affiliates has been my equipment of choice since I returned to bowling last year. I've had no interest in using Ebonite/Track/Columbia/Hammer -- that feeling was cemented 20 years ago, although I still have my original Fab Blue and Burgundy Hammer, and a Columbia Black U Dot and Columbia Pearl Dot. I've not been impressed at all by Storm/Roto Grip/Global 300 stuff. I've been curious about Motiv equipment since they seem to produce stuff with good mid-lane and back-end reactions. Perhaps I'm cheap, and I'm not willing to put out that kind of money for Motiv's stuff.
