I just hooked mine back up the other day, and i love the way it drives now, i had it disconnected when i did my front axle swap,(new ball joints,8 lug conversion,4.10 gears) it was quite weird, swayed alot, especially in curves and even worse in those curves with a decent bump in them. Even driving straight, the truck would sway side to side and got real bad when i hit bumps. I didn't like the way it drove, but i loved the way it flexed when wheelin. I have decided to go ahead with the sway bar disco's. Much nicer ride with it connected, but also sucks now that it is connected when wheelin.
BTW, mine is a Burb, that may have something to do with it, alittle bigger ass, may sway a bit more than a Blazer.
