No strong feelings yes or no, but! I learned to fly in a Cessna 170B - not your conventional trainer There was a day when the only thing you could learn in had a taillwheel and aviation survived. My only take on the Speedster are the CFI issues. It may take a bit more time, but I can't see where it won't be doable, and not having to pay rental fees would be a real plus to me.
