Make the 044 a hybrid and shrink the gap a little! As for a 30-40cc saw, I have a MS250 and an 026, while the 026 doesn't run yet I imagine when it does one of the two will be cut loose. I have no issues jumping from my MS250 to my 562 and I've never wished I had something bigger than my 250 and smaller than my 562. According to what I've found there is a smoking 6-ounce difference between the MS250 and 026, so I don't think it would be worthwhile to get an 021/025/210/250 and 017's are just gas hogs with poor air filters according to my neighbor.Damn 3 saw plan just morphed into about a 5 saw plan. Decided I needed (read: wanted) an 036 Pro to replace one that I ported and sold a year or two ago, so I have a minty one one the way from Colorado.
With that, my "user" saw lineup is as follows: 020 Super top handle, 026 Pro, 036 Pro, 044, 076. If I added to it, I'd prolly get a rear handle 30-40cc saw and an 064 to fill the gap between the 044 and 076...
