Why not keep things simple and go with a decent fixed 4X scope? My choice would be a Leupold, but whatever floats your boat. I have mostly varibale power scopes on most of my rifles today, but as money becomes available, I'm switching to 3X and 4X scopes for most of them. My reasoning is 99 percent of the time the scope is set at 3X. I use binoculars to spot my game, stalk to a reasonable range and shoot with the scope at 3X. Result? One dead animal, and I haven't messed up by having the scope set at 9X because I was using it instead of the binocs. besides, the fixed power is usually a few ounces less in weight that the variable, and at 7K to 10K feet, every ounce saved means a lot. I've gotten too darned old to be packing Hopwitzers up a mountain side.
