MS!
Unfortunately not my strong suit- always relied on AP, Bb, Redcard, and serve- seems things are a lot harder now.
Also with SPG I just could never get the math to work out. MS'ing 10k point for example would be 20 GCs at around $5 each, which is $100 and a whole lot of work. Yeah I could get more than that out of 10k SPG points, but not that much more that the hassle seemed worthwhile. If I'm missing a method or something def let me know, but always seemed tough on that card in particular- esp when I could be earning 5x for free on the ink with enough OM promotions that were taking up my unloading pipeline.
