I have had an Ogio Atlas cart bag for a few years and it has been superb. Nearly as good as new even now, load of space and well thought out. Still have it but have gone back to carrying. If I revert to the GoKart again it will be straight back out.
Got an Ogio Grom carry bag last year after lots (and lots) of deliberating. Have to say it's fantastic. The only thing that's a hassle is the zipperless ball pocket. If you need to tip the bag upside down for any reason (my winter fairway mat fell into the main compartment), the balls go flying everywhere
Other than that it's a very tidy bag if a little heavy. Fantastic quality.
I have had the Ogio Grom for about 2 years now, started with a 2008 and it started to fray a little so sent the pocket back as proof in 2009. They sent me a spanking new 2009 one for no extra cost, only had the 2008 for 3 months!!
No problems since, the only downside is the weight of some of them, pretty heavy for carry bags.
