That would not be an issue for me.
Sure I prefer my 6P for EDC, the metal body has a nicer look, but for hiking the G2 is my choice : seems more sturdy, and I would not care to scratch it (and I guess it would not be easy...).
My main concern with these SF lights is the fragility of the bulb.
Thats why in my backpack there is a spare carrier with batteries and a lamp assy.
