Jugg, High Rollers and tournaments of the like have kept many great bowlers from wanting or NEEDING to become pro. That is a real problem. The Professional level of the game/sport should be the ONLY place ANYONE can make real good money.
These alternate levels of bowling (semi-pro, professional Amateur etc.) have drained the competitive spirit right out of scratch bowling. The ultimate goal of a bowler should be the Professional level. Not High Rollers, TAT, ABTA, etc.
