Rear shock recommendation for 2" AAL and future upgrade to 3" pack

I have a fab tech 2" AAL in the back of my truck now and have been running the factory base model shocks in the rear and they are done so I need to upgrade.

I for see in the future, as my rear springs sag I will upgrade to an allpro expedition leaf pack or an OME Dakar leaf pack which has 3" of lift but this won't be for a year or so.

I want to get shocks now that will accomodate the 2" AAL and a 3" leaf pack, is my best option bilstein 5100's or the OME N182 Nitrocharger shocks?

The truck will be seeing mild offroading every now and then and fairly heavy loads during the week as its a work truck

 

I went with the OME shocks. Ran them with a 2" AAL for a bit, now I have the Allpro leaf pack. No complaints.
