*deep breath*
And just a bit of a soapbox speech... keep in mind I've had very old, traditional mentors that have been showing/finishing/specialing one of the most cutthroat and competitive AKC breeds for decades, so take what I say next with a grain of salt.
This fad of "glitzing up" show leads annoys me.
Show equipment needs to not overshadow the dog - you want the judge looking at the dog, not the collar and leash! So it should always be a color that blends in nicely. I think the bright, glitzy, heavily beaded leads overshadow the dog and are a bit, erm... I don't know. Showboaty. Like the dog needs beads and fancy colors to be noticed. One of my leashes does have subtle beadwork, but honestly I'm too embarrassed to use it except on silly puppies in non-licensed UKC classes. I try very hard to be respectful to the judges, which to me also means not presenting my dogs on leashes that fight for the judges' attention.
In AKC, the judge sees very little of your dog. I believe the suggested time limit is 2 minutes, and usually you don't even get that. Don't waste precious seconds on the judge glancing at your flashy lead. And in UKC, most judges I've shown to do not like "showboating" in any form... so again, out come the plain leather show leads.
