It probably won't be for a while, i only have ~150 miles and need to get it more set up with my bumpers and sliders (and possible roof rack) before getting it weighed and figuring out springs.If you get a set let me know how they work out and a comparison. The price is not bad and I am always on the look out for ways to make the ride better.
I was talking to a buddy who sells sxs parts and he recommended just replacing all the springs because stock springs on any machine are pretty much junk and will sag out quickly.
The $100 pair of springs from bandit is hard to beat though. For $100 you can't go wrong.
