I've been watching a few of Redbull661's excellent videos and also reading the recent comparisons between the ms462 and ms461.
Most videos show that the 461 outcuts the 462, even though there is some weight reduction to the 462. I think most folks will remember the 461 fondly, and not see the 462 as a big improvement.
On the flip side, this video by redbull661 shows that the 661 seems to be superior hands down to the 660 in every way.
What are the Stihl saws currently available that are clearly superior than their predecessors, and which ones aren't?
