I wish I could like mustache and drop bars. I've tried myriad combos of stem height, length, bar rotation, brake lever position, tape type/style, etc., but I could not get drops and mustaches to work for me(Yet. Always fiddling and won't totally give up on them yet.). The best combo so far is an old Origin8 Gary Bar with a tall, short stem. The width is what made them so comfortable at around 560mm end to end. "normal" drops feel a bit too narrow for me. Perhaps I just haven't accustomed myself to them yet? Mustaches also just don't feel right. Too narrow or too much sweep or something. Dunno. The problem is they all look so good on steel bikes, so I really want to like them. Oh well. I think the most ideal bar for me would be an H-Bar type bar. The trekking bars look like they'd be pretty comfortable, but I think they are hideous. Again back to style/function debate in my head. As I typed this I wanted drop bars to work so badly that I just swapped back from flat bars to some 46cm Salsa Bell Laps. I guess I'll keep fiddling until it's right.
Give the bars a shot! If you like them, ride them. Thats what I say.
