it's the part on vbar that I was talking about. if you calculate Vbar it will tell you how stable it'll be. for a high winger that you want to be a nice relaxed flyer then the Vbar shouldn't be too low. a couple of aerobatic planes i built years ago had Vbar of about .35 so It'll have to be higher than that
