RE: Good 2nd Low Wing?
Avistarpilot:
You have made a wise choice moving to a gentle sport low wing before finishing that Decathlon. The GP Decathlon is fast, heavy and loves to tipstall. Don Anderson (President of Great Planes) told me years ago that they had to discontinue that kit because so many people crashed it on their first landing attempt.
The Decathlon is a good looking airplane and you will probably enjoy it once you have the skills to deal with it's nastier flying qualities. (Build it as light as possible and keep the elevator travel on low rates.)

OBTW; The Pulse 60 from Horizon is a great second low wing also.
