The SA can only be used on certain flights and is becoming increasingly difficult to redeem. I had 6.5 (13 OW's) when RR 2.0 and I have just now gotten it down to 3 OW's. I was able to schedule one more today.

I also have 3 credits and I have decided the points are more valuable than the SA I could purchase. I am going to let them die of neglect. But, I have 250K+ points, so I have no shortage of options for booking flights. I have found that the flights in which I can use SA's are the cheap ones that do not require a lot of points. Close in, less than 48 hours, a SA may open up on a more expensive fare.
