I have a Husky 345, I like the saw very much. It has fantastic power, cuts fast and is smooth.
However I had to purchase an 18 inch bar and Stihl chain, as the OEM chain is absolute crap. The cut rate is more than twice as fast with the good Stihl chain!
I got the Stihl full chisel chain, cannot remember the p/n to save my life. The chain is "homeowner" size and as such, there are not many choices.
If I were to do it again, I would go with a nice Stihl with the industrial chain.
Sorry I cannot be more specific, but the chain pitch is different between homeowner models and pro models.
IMHO, the pro chains are much safer, even though this is more risk of kickback. Those homeowner chains cut so slowly and wear out while doing so. Then the homeowner quality chains may just jump off the bar and cut you up. Ask me how I know. I used to heat with wood. Plenty of experience.
