Just fly southwest.
You get three bags, up to 70 lb each, and you can claim one extra bowling bag (any kind of "made for bowling ball" bag or case [you can claim a 4-ball case as a bag... but there is no insurance with these]) as a 4th bag... also up to 70 lb. This lets you be flexible with your stuff.
Southwest may be more expensive, but if you add up the excess baggage fees that you add up, it's the same and with less hassle. I'll take an extra layover or two to Florida or JFK (for JetBlue... its 70 lb per bag but still not 50 like United and USAir), if I can be flexible with my bowling equipment.
The tournaments in december, I will fly Southwest. I will bring looks like 3 cases of balls (sad, huh) and clothes.
