RE: why a cub?
A Cub would certainly be good practice if you aspire to fly WW1 aircraft. I have never really been a fan myself and never owned one, but I have flown them. I am more sick of P-51 mustangs and P-47 Thunderbolts than I am Cubs honestly! With the Warbird craze now, these are very prevelant just because they are easy to fly mostly I believe.
