I've got the Leupold QR base and went with the QR high rings.
All I will use is Leupold QR or QRW bases and rings.

your ring heights are with the QR:
Low: .65
Med: .77
High: .90
As you can see, there is really minimal difference between medium and high rings and the high allows that extra scope clearances.

This allows me to leave the iron sights on and adjusted in the event I need to pull the scope in the field, or if I just want to hunt open sights by simply removing the scope.
