Boss 2.0 Lift Kit on '17 DCSB TRD Off-Road

Im thinking about getting the boss 2.0 lift kit for my truck, and need some more info before i go along with it. I have option of getting 650lb coil or 700lb coil, suggestions? I believe to understand that i can dodge getting new UCA's if i stay under 3" total lift, and I would like to get as close as i can to that. Adding 2" AAL's to the rear as well.
*Bilstein also has a package with the 6112 coilovers in the front and 5160's in the back. This could possibly be another route i could take as well. Same questions could apply to this, just havent really had time to look in depth at the bilsteins.

Both lift kits are just around ~$1300

 

Type either lift in to search box, check this forum only. Lot's of info on both set-ups. Plus it's closer to 2" of lift without after market UCA's, over 2" is when you should install (recommended) new UCA's.
