Well dean at washington pro saw has built a really nice 390xp for me. I ran it this weekend on 5 27inch and up red fir. Me and my brother in-law were both there we had 5 saws. The 390, 372, 346, 441 and a 660. The whole lot of them great saws. We both came away very impressed with the 390 sacket. The New King is here and its a 390 sacket.
