2high2fast - I want to meet the Comanche guru who can land in 310m strips. I thought getting my twin com stopped inside of 400m was tough. The single com might suit me better. It's not much slower than the twin. I rather fancy the PA24-250 as it has the manual flaps. It can do 150kts off grass with the big 6.00-6 nose wheel keeping it from digging in like a R182.
I think all the 4 seat comparables to the 182 have been mentioned.
