New riding layout?

For a while now, I've been riding DF bikes (i.e. Diamond Frame, or safety bike) with the handlebars raised up to be about level with the saddle.

Since this bike was an MTB with a tall-ish threaded stem for MTB bars, I needed to make some adaptations to make it take road bars and brakes. I got a Profile Designs threaded->threadless stem adapter to use with a threadless stem I already had. I figure there's more and cheaper choices available in threadless stems in terms of length and height at this point.

With this setup, my Vetta Race Lite saddle is a few inches above the level of the bars (Titec Malone 44cm drop bars). This is giving me a lower, more stretched out riding position than I've used recently, if ever. In the few minutes I spent riding around the neighborhood, this position actually felt very comfortable. I'd be insanely happy if I can get this low & aero on a DF bike and not be in crippling pain over say a 11 mile commute into work.

Gee, I might end up as fast as I am on my Bacchetta Strada recumbent!

We'll see.
