PA-28's account for 455 of my 650hrs, the Mooney M20J accounts for 170hrs. The remaining 25hrs have been in various Cessnas (150, 152, 172, 172 on floats), Cherokee Six, and DHC-2 Beaver (floats), and the Katana. The Katana is the only stick aircraft I've flown, and very nice to fly it was too!
I've always liked the PA-28, but then, thats what I've been brought up on I guess!
