air suspension reviews.

Ok my fellow tacoristas. For those that have chosen and air suspension upgrade over springs or AAls. What pressure works well for the daily driver and some towing. I dont want a harsh ride..that has been shared here in reference to some AAL and spring packs. I had a tapered or might i say a 'progressive" leaf added to my stock 93 xtracab 4x4 PU and it was perfect. Why isn anyone talking about this kind of intermediate approach versus ..I got the "brand " / i love these guys...uhh make my truck look 'whatever...not seeing any tech or brand fitting this niche here on TW..Am i left with a harsh ride and having to go beyond the 5100 bilstiens at 1.75 to level things out because of the rear height if i buy a "PACK". I see but one option left a, and that is to employ an airbag system. So what say you all..chime in on your experience with an air-ride system with and without a load during hauling and towing. For the rest...is there any one out there that has a "progressive"single leaf response to a need for more "Loaded" condition without riding like a brick unloaded...My 93 never bottomed on the the overload spring even carrying a 500lb motorcycle and towing a 2000lb trailer like my Taco does. Yes ..I have the TSB and BIllys in the rear...Let the knowledge flow forth now!!...Thanx
