gphil,
The LT410 is a good plane. Not trying to be a smarty pants but what it sounds like is you need stick time. Maybe try throddeling back some
and slow the plane down. Don't know if you are a thumb flyer or not, but if you learn now with your fingertips you will find things a lot smoother.
Jusy my opinion but I don't think dehideral is gonna make that much difference.
