Keith,
I am sure that you have seen the back cover of the LE Plans that shows the WL of the main gear axles to be -22. I believe that this is valid for the small tires. When I built my Long-EZ I was using the 500X5 tires and realized that if I kept the -22 WL, the plane would sit at a negative angle of attack. So I moved the axles up, a little over 1 inch, making the WL about -21. I believe the Cozy builders also shortened their landing gear but you should talk to someone to confirm.
