I see a lot of debate on what a good 1 -2 punch is for firewood saws if one were to have only 2 saws....or for that matter just one saw! Anyway, does a 346XP (18") and a 365 (20" or +) a good combo. Anybody running them? I have a particular 350 which is 6 yrs old and is staring to give me issues. Might set myself up to have a combination like I mentioned. Thoughts?
