I wouldn't go too much more than "Slightly" - This is a Decathlon, It's just as likely to do weird things if it's balanced wrong either way.
What is better?
To balance with a full tank of fuel or an empty tank?
I balance mine at the sides of the fuse and also at the wing tips then make sure I have a straight line between the 2 points.
When I removed the nose wheel I moved the battery toward the front and I have 7* nose down.
