Like I have said previously, the saw you like best will be partly dependent on what it is you have cut.
For the smaller trees, will usually do it all with the 026 or 261. For milling, I do most of it with the 066s.
And then there are all the rest of the saws for the stuff in between!
In a log pile, I will usually pick a 60 or 70 cc saw with a 20" bar.
