I played with an 8 and a 7 tooth on the 651's. I think I've settled on the 7 tooth, unless your just cutting really small stuff. The 346 does crank out the rpm's though, more so than the 651, but a little more raker depth on the 651, and it's a close race. I'd sure like to try one of those little Echo's. I wasn't too impressed with the stock power of the CS-670, but have always liked the feel and the construction of the saw, and after porting, it's not bad.
