Which Shocks for rear TSB + 1.5 AAL

Ok i'm curious on what shocks everyone is running with a rear tsb and 1.5 aal.

I have a db cab long bed with the tsb. Origanlly I was planning on getting the 5100's on all corners and setting the front to .85. Well with just the tsb spring when I was hauling the other day I noticed I was front high with 30 sand bags right by the tailgate. I think it was about 1,500 lbs which may have been to much. anyway... I'm planning on getting a boat soon and don't want to be driving around nose high. If I raise the front more, I risk the chance of doing that even more. I was thinking about air bags but would be nervious to do any type of dirt trail/offroading which could cause damage.

I talked to DSM and they gave me a few options for shocks which were
regular 5100's, if I run these I could top out the shock and damage mounts and i'm limited on droop.
or
extended 5100's, If i run these i risk bottoming out do to the collapse rate with the 1.5 aal.

I just want to get a good idea of what everyone is running with this setup and how does it handle? Should I not go with the aal and just get the Firestone Ride Rite airbags?
