The biggest weakness with the standard Leupold (Redfield type bases) is the windage screws on the rear base. I've also seen the the front ring shear off from a moderate recoiling rifle. They tend not to hold stable on moderate to heavy recoiling rifles. ie: zero shifting over time. The dual dovetail type bases are the best way to go with standard bases.
Another design that I have grown fond of for packing rifles is the talley lightweight integrated mounts. I have a set of Talley's on an M70 300 WSM and I love their clean look and simplicity.
A picatinny setup is generally more stable than the standard design. There are some high quality choices for a picatinny setup. You can go one piece or two piece. The one piece gives you more options as far as mounting, also it's ultra easy to remove the scope and transfer to another gun with a picatinny rail if you so choose.
Keep in mind the M70 WSM action is a specific length when ordering a one piece base. A couple bases that are available are Nightforce, Warne, and EGW. The Nightforce and Warne are steel bases, and the EGW is aluminum. As for rings there are a lot of choices, Burris Tacticals and Signature Zees, Warne, TPS, Nightforce, just to name a few.
