Questions on reliability of bag setups

[adpostel]

OK Guys, now I have a couple of questions...

1) When you are talking about an airbag suspension, are ya'll using like a front, back, side, side adjustable kit, or are yall referring to bags instead of shocks that can be adjusted.

2) For the guys who have been running on bags for a while, how is the reliability of that type of setup?

I want to lower my 68 to I guess a 4/6 drop and can probably do it with a static drop, but what would be the pros and cons with a static versus bag drop. I would hate to have to roll into work with a problem and have my ass end up in the air and the oil pan scrapping the ground or vice versa. What are some of ya'lls opinions on reliable bag setups, and comparable statice drops?
