Hey everyone, I have the same old question. I bought the triaxis the year it came out 91-92? I'm currently looking to buy another. I hear the phat mode is no good? this pertains to what? what channel does the phat mode utilize and what does it do to it? are there any other differences between the V.1 and V.2 ? Someone suggested that the original triaxis is the best one, something to do with the circuit board? is there a way to identify the units by the serial number? Thank you very much to whomever takes 2 min. out of their day to help me out.
