Hi Kevin, sounds like a great name for a Helilogging Co.
Someone asked me recently about the Canadian chainsaw, but I lost the thread. I appoligize to anyone who may have asked me a direct question and didnt get an answer. Its just that this forum is very fast and if I open a thread with the intension of answering it later- well, it just gets lost somewhere, like dozerdans reply about steep slope logging.
