I had a similar dilemma when building my recent wheelset (Kinlin XR-200 or XR-300). I figured it this way: The aero difference is only 8mm (11mm in our case), which is not much. The weight difference is 130g (140g in your case), which is not much. Since it didn't matter much either way, I decided to go with the XR-200 just because it would be fun to tell people I had a set of 1375g clinchers. I also figured if I were to go aero, I would go all out and at least 50mm deep. The clincher (pun intended) was that I'm so slow, aero doesn't help me much anyway. The only thing I tossed out is that deeper rims tend to be stronger.

There's your food for thought.
