I really like the plug-in tt levers. If you get one, make sure that the handle is as long as possible, so you can adjust your hands further in or out on the brake to get different leverages. I use a cyclocross lever in the same place on my geared bike, but only because I have barcons plugged into the ends of the horns. The angle on the corss levers puts them a bit farther out than is ideal.
