I used castering tail wheels for years and Yes they can be a bit trying now and then but I like them and can see no reason not to try them. They are easy and make you pay attention to what you are doing. It can't hurt and it's cheap and easy.
Just remember that you have to do a lot of the steering with the throttle and rudder, and full power is not your friend most of the time. I think it is a challenge to be able to taxi a swivel tail wheel plane and when you get good at it it gives you a lot of pride.
ENJOY !!!! RED
