For some reason I think I need more saw and have been thinking of selling my 390 for a 460. My 390 has never let me down and to be honest I still use the safety chains, so im sure it would cut better w/ a chisel chain. I live in Eastern PA so I run into the occasional large oak but mostly cut ash and maple w/ a 20" bar on the 390. The weight of the two saws is close w/ the 460 being a bit heavier but also having alot more power and also giving me the option of putting on a bigger bar for the occasional monster. So should I take the plunge and get a sweet pro saw, or maybe port my 390 and start using chisel chains. I should also mention i have never had the pleasure of using a pro saw so I dont have much to compare to my 390.
