Ken,
I'm not sure I would claim similarity between the Banshee and the Magician for this particular issue. The Banshee has 1-1/8" wing asymmetry whereas the Magician has some huge number--something like 3" from memory. This affects tip weight.
I wonder what you else you were compensating for on your Magician if you needed a ton of tip weight? Just curious....as I have a Magician kit that I may someday build. But, I would probably cut the offset down to something around 1/2 to 3/4 of an inch.
