I have a Husquvarna 357XP saw. Love it. It has a 20" bar on it. I predominatly use it for bucking firewood, nothing much larger in dia than 15" typically. Thinking about getting a 16" bar and chain for it. 20" seems to be a waste. Curious to know if anyone has gone to a shorter bar what the performance is, noticable? I would expect that the sw to be alittle faster? Not tht it isnt fast enough already but time is money!
