Keep it Simple: 3-9x40
The AO adds weight and length normally. Just another thing to fiddle with.
If you are going to target shoot with the same rifle and wanted to save money then get it and set the AO to 100-150 yards and leave it at 4x while in the woods.
Otherwise, consider the Nikon, for $290 at Midway you could get the Buckmasters 4-14 or the Monarch 3-9. In this example you would get a much better set of lenses and guts but with the tradeoff of fewer features (no AO). IMHO
