RE: Dual Dove tail or Standard setup?
If you have easy windage adjustments on your scope there's no real reason to go with the standards. I prefer the dual dovetail as I feel that they're easier to install and align. My buddy has the standard setup on the exact same rifle. Neither has presented any problem. I picked up a lapping/alignment kit from MidwayUSA.com to assist in the installation. A good tool to have regardless.
