...Do know one guy who prefers the WD to the standard Duplex because the crosshairs are a little heavier. Apparently he's still wandering in the 1950's.
My Leupold VX-5 2-10 has the wide duplex with the heavier crosshairs. It's on a Tikka T3x 6.5 CM and I've found it okay on more precise long range shots at deer. Haven't used it deer hunting in the bush yet though.
