I have three days (minus insane TW) for an artifact to upgrade so that I can then level-up that to insane and finish my 2nd Super-ascension. My question is what dig should I start when I Super-ascension? I'm guessing it's between an 100% common and an 89% uncommon dig site. I can see pros and cons with both. Also I'm a snail at this game, so take that into account and I'll be keeping 2 insane (1 upgrading) and 50% AP.

Digs dont carry through SAscs

If your asking what dig to do right after you super...Well you need the seven artifacts I guess you already have two of them so getting the remaining 5 is better to get as many common as fast as possible. Once you get the set of seven I prefer uncommons.
