Cork tape and give them a bouble wrap and you will not feel any discomfort at all. When you do put them on, I think you may be more comfortible to have them pretty close to level. If you cock them to much you'll have a tendency to lean on them to much and pinch the nerves in your hands. I have mine 1" lower in the back than the front. My saddle is 40" the back of the bar is 41" and the front is 42". You'll probably have to play with them a little, just like everything else, but you'll know when you got it. Your hands shouldn't tingle of fall asleep, if they do, just move them a very little at a time.
I think Nashbar has about the cheapest bars and all the others are so close it doesn't make much difference. Sometimes when I look through their web site, I see that they are out of them, so somebody must like them besides me. Good luck.
