Lowering a vehicle and ride quality don't really go hand in hand in most situations.

For example, whether you used cut springs, or actual lowering springs...both with result in a shorter overall amount of travel. This means that you'll need a stiffer spring rate to prevent coil bind or bottoming out. As you can put together, a stiffer spring means a less comfy ride. In the case of the cut springs (same rate, just shorter) it means that you'll be more likely to bottom out.

With a lowering spindle, you retain stock geometry and springs, so your ride quality won't improve, but it also wont' get worse.

However, since technology has improved in both springs and shocks, you can get an acceptable ride quality. A good set of shocks that are proper length for the amount of drop you have, is probably the biggest factor in preventing the harsh/bouncy ride most commonly associated with lowered trucks.

Also consider that a smaller wheel with a larger tire (like a 15"), will have a slightly softer ride because the larger sidewall soaks up some of the bumps.

Bagged trucks with a well measured link setup and bags that are correctly sized will be the "ideal" way to get any amount of drop, and actually improve the ride. A badly setup bagged truck will NOT ride good, so the emphasis is on the quality of the parts and the install.

I'd say my truck has a fairly acceptable ride for a hotrod, and I'm about 4/6 with good shocks and a 15" tire. I've got a screwed up back, and in combo with my ProCar seats, I consider it comfortable enough for my use.
