Here's a good thread about Jumbo Drifters and brackets. I think if you get a bag with plastic backs and don't somehow support it by the bottom (or manufacture a real back as Phil has done), if you put any weight in them at all, they'll eventually crack. I got the bag brackets with bottom support from Bella Corse and will see how long it takes for the bars to snap. They're over a year old now and the bags carry quite a bit of weight.
Got tired of the drill after going through 2 sets of Saddlemen Drifters. They do look good, and have a great warranty.
