FWIW, I use a very short and high upjutter threadless Profile on my 17" Monocog 29er with grossly overlong tt and by pure serendipity it closely matches, albeit with much higher bars -- Salsa Bell Laps -- the drop position on my Rivs. (Actually, it mimics the new Sam Hill very closely, with bars 1/2 to 1" above saddle.) The handling is a bit light when I sit up with hands on the flats, but I usually use this only on downhills anyway where rearward weight movement is desirable. With the high bars, the hoods are close to the flats position on my Rivs and the hooks rather like the hoods.
Here is a photo of the Monocog in its original setup; it is presently at The Shop being brazed on by a local builder and will afterward be named the "Silk Purse." http://picasaweb.google.com/BERTIN753/DropBox#5391043633214271410 Note that the Monocog has something like a 24" effective tt so that, with saddle in the same position vis a vis the bb shell (it, waaaaay back) the bars have to be immensely higher and the stem immensely shorter than the 8 cm 2" below saddle short 'n' shallows on the Rivs which have 57 cm effective tts. Note that the 17" Monocog is the *medium* size and fits my long-torso'd 5'10" bare feet height very well. FWIW, the new 56 cm Sam Hill has a 59 cm eff tt with the stock 10 cm stem and, with bars set like those of the Monocog it fits fine, as you might guess. But it, too, feels light when I ride on the flats, leading me to think that it is less the reach of the stem than the height of the bar that affects front end handling.
