I got some new handlebars (3T Ergonova Pro) for my CAAD10 and after getting the handlebars centered in my stem, have had great difficulty deciding where to put the shift levers, alignment-wise.

Not only can I not figure out how to level the handlebars (as there's really no flat spot on the tops to level with, so I did this based on feel in my hands), I can't figure out how to center the shift levers (Ultegra 6700 STI Levers) horizontally on the bars and equally (so they're not pointing at a weird angle outwards/inwards).

Is there an easy way to do this? A good guide/video? I've spent over an hour making adjustment after adjustment and still not getting it to look good to my eyes, and I'm getting near the point of paying my LBS to do it all for me (although I'd rather not).

Here is what I've settled on after giving up for the night (keep in mind the front wheel is slightly elevated in a stand/holder):
