Worried Guy is my sling guru, so I'll endorse everything he said. The AdVance sling is the way to go, but you definitely want a very experienced surgeon doing this. Don't believe the line that it's an easy peasy, minimally invasive surgery.
On the other hand, it does work great for most patients. I didn't experience the long pee times that Worried Guy mentioned, but then Worried Guy paid the doc extra to pull the sling extra tight with heavy duty vise grips. I didn't get myself all cinched up real tight like a rodeo bull, but the thing still works pretty well.
