Columbia has a great sales tool on their Web site, comparing the Columbia 350 and 400 to a Mooney Bravo GX, a Beech G36, and Cirrus SR22.  Just for grins I am adding a column for the Lancair ES-P.  One bit of performance data missing from the sheet is time to climb to flight levels.  Since I am starting with a nominal 400 hp I believe that my ROC would be similar to that of a IV-P.  Would any of you TSIO drivers have a time-to-climb to 18,000 ft?
