I want to replace my springs. Are bags the way to go or lowered coils????

[71Seth]

The springs on my 71 have been heated in the past. Then someone put some of those coil spring twist in boosters in to try and get it driveable. I want the truck to set low and level. Should I go with a lowered spring or bags? I know a dealer for the bags and can get them @ cost. Is the end result worth the time and money? How much better will the ride be(night and day diffrance)? If I set the bags up on a indepent 4 coner system will this help with body roll?

Sorry for all the diffrent ? but I know you guys aways have the answers to them.
