You put on the bars that feel comfortable to you and you mount them in any position you like that will fit on the bike. Clip ons offer much a much wider range of possible mounting positions than fixed bars, but all of them relatively low. That link to Flanders, in the post above, is one well worth taking a look at. Flanders makes bars you and I haven't even though of yet. Also, when you eventually get around to looking at widths, rise, and pullback be careful, all manufacturers do not measure those things the same way and so sometimes its very difficult to compare bars just by the numbers.
