the geomerty of my old kestrel was designed by TK, I must say the bike fits and handling is pretty neutral. 100mm stem, and a seatpost that is not too long. I currently have 3 road bikes and all handle really nice, but I prefer the kestrel so far. I recently got a rock lobster cross bike and it is real fun to ride. rock lobsters are built by paul sadoff, one man shop and the real deal. I just bought a rock lobster road frame...I'll report back on how it rides...might take a few weeks.
