Dear Mike,
It's only been a few days now since I first started using prestas, and why you ask? Some feel that they look sharper on a bike (I tend to feel the same way), some feel that there is a weight advantage (I'd have to see the evidence on that one), but my sole reason for converting is the high pressure thing (I want my tires at the maximum level that they can hold). I've got high pressure tires, and the schreaders just wouldn't hold it for very long. The prestas seem to be doing better -- knock on wood.
Believe it or not, I'm still using my frame-mounted schreader pump. I can't see buying a presta pump when you can get a presta-schreader adapter for a buck; you just screw it onto the end of the presta, and bada-boom! Instant schreader! You can keep it, as a couple guys mentioned, on the stem or under the saddle, or like me, in my wallet with my change.
But in all reality, if you're not into high pressure, I wouldn't even worry about it. The important thing is that you're riding, and having fun doing it! You're cool Bro; I hope to talk to you again sometime.
Sincerely, Jeremy
