Ride and handling of static drop vs airbags

[Overdriven]

My 67 lwb came with a cheap airbagit.com fbss kit installed by the previous owner. With 60psi front and 30psi rear it has about a 3/5 drop and the ride is nice, it's not Cadillac cushy but it doesn't beat you up like my totally stock 06 XRunner does. The shocks could use a little more rebound but they're crusty oldies, stock length on stock mounts and stock track bar so those need to be addressed either way. There's also no sway bars, no power steering and non power 4 wheel drum.

Power steering can wait until I swap out the 6cyl but I've decided not to wait until winter to upgrade to disc and rebuilding the suspension. I am likely going with the 4 wheel 12" disc kit from POL with a set of 18x8.5 and 18x9.5 wheels. I don't care about going up and down, 3/5 or 4/6 is as low as I want to go and I want to keep about a 1" rake. But how good is the ride on a static 3/5 drop? How good is the handling on airbags with sway bars? I'm not looking for an autocross monster but I would like the suspension to be confidence inspiring when taking corners fast and not beat me up.
