I hated my rolling thunder....the pockets all ripped within the first half of a season, the zippers are crap and stitching is terrible. When I mean all the pockets, I seriously mean all of them.
I tried an ebonite grand tour stackable, probably the worst bag ever, the handle would break monthly. Now ebonite was great, they sent me a new bag free of charge 3 times....
This past season I bought the KR Royal Flush, I love it! I dont find it any more bulky than the rolling thunder. Its made great, zippers and material are excellent and the handle and wheels are built like a tank. Went through the whole season and it still looks like brand new. I liked it so much I bought a 3 ball roller and 2 ball tote, all royal flush, all match.....plus a 7yr warranty on all of them....i have more room in the 4 ball than i could use...
