Well, the guy asked for the lightest post, neither the strongest nor the most durable. I'm guessing he's aware of the trade-offs. I have heard great things about the USE Alien posts, but some complaints exist about the actual clamping unit breaking off, supposedly the post is real strong and so is the clamp, but its attachment of the two could use some work. Something they should look into fixing in the upcoming year/years. Still, I do agree that the USE Alien may be the best bet.
