Hi Jim,

I too am looking the "do it best" bearing as they also stock the #08200 magicsliders (I plan to use these a the breaks) which saves me shipping and are supposed have the right height for the intelliscopes. I'm really glad to hear that you found the thickness to be perfect!!

Have you tried using your XT12i on a sloping surface after the mod? I would like to find out if the shift in the center of gravity of the scope due to the slope has any effect on the performance of the bearing.

Do keep us updated on how your break mechanism goes.

Thanks again,

Sabir
