I'm unlikely to ever trade off my Cessna P172D, but it's really poky compared to any of the Mooneys. I have a fair amount of time in a C model--enough that I can smoothly operate the gear

--and about 150 hours in a K model (231). If I wanted a fast traveling machine, a Mooney would be high on my list, for sure.
The only time I have landed a Mooney on a rough strip was on a ranch strip near Walsenberg, CO, to drop off the owner's wife. Landing and taking off was easy, but I worried about striking the prop while taxiing. The Mooney is fairly close coupled, so that it bobbles a lot on rough ground.
Mooneys really demand good speed control. The typical error which leads to crow-hopping and prop strikes is coming in too fast and trying to force it down. Come in slow enough, and it's an easy airplane to land. I routinely took both the C and the 231 into Lee Schloredt's strip near Sundance, WY, which was 2100' x 20' at 5000' elevation.
