Anyone ever consider it's not the equipment…. It's the bowler?.
Typically whoever has the most bowlers under their brand usually ends up "dominating" said event. If Belmo or Liz Johnson win tournaments X, Y, and Z using A, B, or C what does that do for me? Considering I throw it nothing like either, and don't bowl either tour… I'm guessing nothing different then any other brand.
I loved Brunswick for years and switched to EBI and noticed zero difference. The only reason I switched was for a little more variety across 4 brands. If I went back to Brunswick brands there would be no issue. If a company makes bad equipment they will be out of business quickly these days.
