I'm 6' 180# and I flew the 150M and 152 I had with the seat all the way back and usually with my shoes off for a little extra leg room.

I guess only way to know for sure would be to find one to sit in. Better yet, buy someone some fuel and go fly for an hour and see how you feel. Remember your passenger with longer legs will not have as much room as you with their feet off the rudder pedals
