If I could only have one saw, It would have to be a GOOD 70cc.
Two saws? Add a GOOD 50cc.
Third saw? A VERY Lightweight 35-40cc saw, well-made, with good power. "brushing saws" are Very Handy to me.
The third should be a 60cc saw, to fill the gap between the 50 and 70cc ones - or a 90cc if the 70cc isn't large enough (it is in my case).
If the 50cc saw is the right one, there is no need for anything smaller - unless you need a top-handle.
