I know some of what your mean. I started flying the Focus Sport over a year ago to try to improve my skills. A month or so ago I was getting rather tired of the continual practice of "making it better" so decided to get out a "fun" plane that had been sitting in my garage unused since I bought it maybe 12 years ago. It is a lot of fun with the retracts and flaps but I know that in a week or two, I'll be flying the Focus sport again. This time though I will trade back and forth. I know that continual and constant practice with the same plane is the way to do well at contests but I'm not into competition (other than with myself!). I do want to improve my skills and the Focus sport has definitely helped with that.
