I wouldn't but I'm biased to the punchy Zeiss glass.

Also, if you ever like to do closer work the Hasselblad w/tubes or one of the superb makro lenes Zeiss offers for this system is hard to beat.

I guess it boils down to weight and if you do closeup.
I'm not sure what a 67o outfit weighs but I'm betting its a bit lighter in the field.
