I put about 10 on my tree last year. Man do they sparkle. They are a little heavier than regular ornaments but if you put them deeper down a branch and not on the tips then they hang excellent. All was well until my cats knocked them off. Doh !
Definitely Z for me! A couple of Studes, also. One for me and one for my Dad. He once had a Studebaker Hawk back in the day. Camaro, Toronado, Mustang and a Kharmann (lotsa luck on that one!) are also on my Christmas list this year.
