Not that it applies to anybody in this thread (except maybe Jack), but if you plan to race Hobies, electrical conducting tiller extensions are prohibited. No aluminum or carbon fiber allowed.
Hey Matt,
Since I only use the 20 for distance racing, it doesn't really matter, but I tested my carbon core CST extension and it does not conduct electricity. As you probably know, they are heavily coated with epoxy. Without grinding away the epoxy outer skin, i don't think it should be considered a conductor and hence, not class legal however.
The rule does not say "no carbon fiber".
I would say that aluminum sticks definately wouldn't pass the intent of the rule, which I understand and support.
