Shifters, bars, stem and saddle should all be parallel to the same plane, if the frame has traditional geometry then it should be the top tube, if it is a TCR, then throw it in the bin and start from scratch.
One of the reasons I like the Gios on the previous page so much is that it's my size (an aesthetically pleasing medium-sized bicycle) and with my preferred set-up of compact bars with flat transition to the hoods.
