Thanks for the replies everyone. A buddy told me to go with the one piece mount because he felt it was more solid. After reading what bigbulls advised about the one piece I'm thinking of going with a 2 piece instead.

TomFromTheShade, I did go the the leupold website and it listed several options for my set up. Not sure now if I should go with the STD mount or the dual dovetail. Maybe I should start a poll.
