BT,
Lovely build.

One thing you mentioned has struck a nerve, Air Shifter.

I was looking to fit one to my 1500 Wing (sagging shoulders and drooping head).
Do they really work as well as they say, and how do you select neutral?
Do you use a tank for the compressed air? As you most probably know, the Wing has a built in compressor for the rear shock, I was wondering if that could be utilised, or does it require megapsi?
