I'm not buying either, but I'd pay the difference to get an alien because I like personally like lugs. I would like to know what tubing it is and what it actually weighs though.

The $350 complete is a myth anyway because half the parts on the TT you would probably replace right away (tires, seat, pedals, bars, cog) or are crap that you'd want to replace (wheels, crank, stem). So if it's the difference between a $500 build and a $600 build, suddenly it doesn't seem like a big difference. You Kilo TT guys all paid $50 more to get a lugged fork, didn't you? Is there any point to that besides it looking better?
