So a handful of years ago, I ended up swithing to 0.058" chain on my 350. Not sure why I switched really. That was probably the time I started using a full chisel as well, but that aside.....why would one do this? For example, if I were buying a new 346xp (which i may do) and the dealer gives me the option of what chain and I get a spare of the same.....what should you do. Keep in mind, I have equal of everything at home...so it doesn't make any difference in trying to keep the same equipment going. I've run full chisel on several saws that I own or have used and like that a lot...so that's kinda decided and on a 346 on know the pitch is .325, but what everyone do for the bar/chain width? If one could get whatever they wanted...what performs better?
