Go with the 20MOA base. It puts your adjustments at 1K near the center of the scopes adjustments which is reportedly more accurate/repeatable. Take a look at Seekins Precision bases and rings. I put the base on my 300 Ultra Sendero and it is a very fine piece. He makes great stuff and he's a great guy to deal with. Best of luck.
Ignorance is bliss...unless you're aware of it.
