I think 'odd' patterns are more likely to be asked for when in a handling class, unless the shape of the ring dictates a reverse triangle - it's all about not getting between the judge and your exhibit, and some Breed Shows will like to have the ring set up so the people watching see the dog - which may mean this pattern has to be done. Just be ready for anything, including switching your dog from the left to the right, so you don't get between judge and dog.
I tend to think if a judge can't feel and then confirm by moving without 'fancy' patterns then they maybe aren't up to the jub - one for the little black book!!
