You know guys, I am rather fascinated, how many posts this thread already has, on such silly topic of what the shape of the tail should be, when carried high up
It is a pity, that there is not so many responses, when the shy character of the dogs is discussed, or that owners should work with their dogs as well, instead of just dragging them around dog shows.
I can tell you one thing - I´ve been on plenty dog shows or bonitations in Czech republic, judged by experienced judges, CSW specialists. And not a single judge paid any attention to in what shape the dog carries his tail, when excited!

Because it is not important thing at all... The only thing the judge penalises, is the so called "hook" on the tail, which is fault that is seen only if the dog carries its tail down calmly.
Unless the tail would be carried like in basenji, which would indeed be weird, it is of no importance and there are much more important things in the standard, that should be followed and concentrated on!
Great faults like dark eyes, loooooooong tails, looooooong ears, black masks, light heads, missing teeth or character faults like great shyness - that´s what you should discuss and try to avoid in breeding. These are important faults against the standard and they make Czechoslovakian wolfdog to look either like German shepherd in wolf-grey colours, or worse, like a shy jackal.
