For as open-grained as it is, Wenge is a surprisingly dense wood. It's heavier at 54 lbs/ft3 than Maple (44 lbs/ft3) or Oak (44 lbs/ft3), neither of which are often used because of that. So, a Wenge Strat body w/ a Pau Ferro top would make for one seriously heavy hunk of lumber. Add an Ebony (also very dense) over Wenge neck, 3 pickups, any vibrato bridge and locking tuners, and you might be talking about a 10 pound instrument. A typical Strat is usually between 7-8 pounds, so it doesn't sound like a lotta difference, but that extra 2-3 pounds can be killer.
