Proprietary products-yuck! Maybe you could visit the LBS and sit on some bikes with diff. bars (or see how the bars on some of your friend's bikes feel) until you find a bar that feels comfortable. Measure the width, rise, not sure how you'd measure sweep, but get all the info on the bar you can and purchase an inexpensive bar (in case you don't like it afterward), and if you do like it could go for a better bar later. I'd go wider at first, with a bar that could be cut down.
