I've never flown a GWS Spitfire but by the reports I've heard they are pretty good fliers.
They would probably make a good Low wing landing trainer - especially to get you used to the higher landing speeds that may have daunted you a little so far.

One trick that I use to get people familiar with higher landing speeds is to get them to land further down the landing area than they are standing so they are looking at the tail of the plane. I mention this for small planes on large landing areas it isn't good if the landing area is only just big enough to use for the plane you are flying. That way, the plane is moving away from you and the speed isn't so daunting. The minus is that you are wasting some of the landing area. The plus is that you learn to make accurate landings with less chance of a go around. As you get used to it, move your landing point further up the runaway - a little bit each landing and before you know it you'll be landing while looking at the nose of the plane and not thinking twice about it. I hope that description makes sense.
