If(let's be clear that's not the plan), but if I had to go with a 3 saw plan, it would be 50, 70, 90, or 35/40, 50, 70. For jobs I typically get by with the latter, a 90 sure can be nice on a big solid stump, but a ported 70-79 does real well.
What I dislike about the 562, is it's so close in weight to the 371/371, then if you compare it to a 462
. That being said, it's sure nice to head out to cut with a bunch of saws that are all fueled up with sharp chains, you sure can get a lot done like that.
