So what if the equipment wasn't urethane, but a brand new Black Widow Bite drilled NEGATIVE?
To the average player, the BWB is a hook monster plain and simple, if drilled normally. Drilled this way, on most conditions, it would be pretty tough to score as normal. It would be a good tournament ball, but on a THS would be pretty worthless, unless conditions were perfect.
What if one bowled the entire league season with his tournament arsenal, one ball per night, regardless of how it worked? Knowing that this arsenal would be used in any tournaments bowled in, would this be bagging?
Bagging, according to the rules, is simply a matter of intent. If you intend to improve your game and try to the best of your ability, you are not bagging regardless of score OR the potential effect on one's handicap.
Does this allow for loopholes? ABSOLUTELY. But sadly true intent usually cannot be determined to the point of bringing charges of bagging and getting them to stick.
