You don't have to put too much thought into bags. Most bags can last forever. Most bags in the $85 to $100 range have 5 year warranties. If your budget is $90 to $100, just pick how many pockets you want and color.
And if you're just getting into bowling. That two ball bag will eventually sit in the garage after a year of use or when you buy a third, 4th, 5th, 6th, 7th, 8th, 9th, 10th, 11th, 12th, and by the time you get to this point. That two ball bag will probably be sold on eBay......HEHEHEHE
