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 conducter 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. [/quote]

You are correct - the rule doesn't say "no carbon fiber". When the rule went into effect (late 70's as I recall), carbon fiber was still rediculously expensive and nobody ever thought if would be used for something as frivolous as a tiller extension.

There isn't a standard conductivity test for the tiller extensions, nor is there a prohibited material list. It's something the IHCA Rules Committee should consider.
