Hey, I have the Storm 4 ball bag, and it is a really good bag. Holds up well and takes a lot of abuse. One other suggestion though if you bowl a lot of tournaments, you might want to go with 2 2 ball totes. They are easier to get around, weigh less, and are cheaper. I just finished my first year of college bowling and took my 4 ball bag with me, it was just so hard to get around. I switched to totes, and it made my life easier. Thats just some advice, but if you want a rolling 4 ball bag go with the Storm. I had it for 3 years and its still going strong.
