Bolo556 I haven't printed any 2A parts with ABS, but my understanding is that it will often have poor layer adhesion for 2A purposes unless you use an actively heated print chamber. Layer adhesion tends to be the weakest link for these purposes. If it's your first time printing 2A parts, start with PLA+/PLA Pro. Most brands of this should be fine but I have had good luck with and heard good things about Polymaker, SUNLU, Duramic, and Overture PLA+ filaments.
I haven't learned much if this stuff from one particular resource, but I would say some of Tim's videos plus the paper he recently published studying the differences between various Nylon and PET filaments have contributed a lot to my understanding of what is important for these kinds of prints.
