7 Wood Vs Hybrid. A hybrid is better from the rough and its also more forgiving. Hybrids of about the same loft are better for bad lies in the rough, slightly more control with the shorter shaft, etc.
I think the preference is. A 7 wood will have a higher flight and thus more stopping power when green hunting. A 5 hybrid is going to have a lower, flatter flight than a 7 wood but it will produce more roll.
