Jim , as a guy who's had a variety of different type planes , I still say as you do that the 150 has character as well as having the right porportions (especialy the TD's).

I learned in a 68 like the one I have now , it was a special time in my young life in 79 .

I still have memories triggered by the site of a 150 , as does the smell of av-gas . crazy
I've had alot of expermentals , and I'm sure some will still be around in 40 yrs , but not in the numbers that our planes are after 4 decades of flight !
