Considering FS 2 Crew for PMDG 737

I personally love it and wouldn't fly without it. I just have the SOP 1 and the animated FO addons for the 737 but I love the 737 version. Really adds a lot of immersion. If you fly the 737 a lot it is worth it, the airbus version I will have to admit I didn't like as much (but its been a year since I used that one so it might be better now) but the 737 one is great. Like others said you don't need to have the animated FO. I would try it without the animated FO and then decide if you want it from there
