I find this very confusing. Under what circumstances should you have 2 A choices? Or is it just if you feel like it? I've always just had one A on green/original...
Oh okay, I had no idea I could have two if I wanted, I never really understood why one or two, why not just two As and two Bs? Maybe I'll email SW and ask!
Possibly they say 1 OR 2 because years ago it used to be 1A +2B as a standard and no option of having 1 or 2 A's. I guess they introduced the fact that you could have 2 A's, but also wanted to say that it wouldnt affect your losses if you stuck with having just the one..... leaving it entirely up to you if you wanted to have 1 or 2
