I have one and it should hold up OK. I don't have it on yet so don't know about how it will fit and work, but have heard no complaints on the net.
There should be no functional difference between it and a solid 1" bar, just the weight. I had the money so I went for it.
If you are on a tighter budget, I doubt the weight difference would matter.
