Ranger School Before SFAS?

[Gusto16]

I just want to start this off by saying if this is not a good question to ask or it should not be asked, just say the word and I will delete it. The last thing I want to do is get off on the wrong foot. Anyways Im currently in the 82nd ABN DIV as an 11b , 19 years of age and am looking for some advice from then men who would know best. In the next 1- 2 years I would like to attend SFAS , thats my goal and I am preparing now. The thing is that I could go to Ranger School almost whenever I want , assuming I pass SURT. So my question is do you think it is smart to go to Ranger School first and then go to SFAS. Or solely focus on preparing mentally and physically for SFAS? Any advice is greatly appreciated. Thank you and have a good day.
