Harry. I have 6 chainsaws I use. My smallest is a Stihl 0/17 with a 12" bar it's light and does a great job on limbs etc. a poulan with an 18" bar and that's the saw I use the most but odd enough it's also the saw I love to hate. Then a shendaiwa 345 w/12" . It's light and dependable but not very powerful. Then an Echo with a 20" heavy bar which is a good log saw. Now my sweetheart is the Makita (dolmar) i4000 equipped with a 24" roller bar . It s a great all around saw. I use it and the poulan "wood shark" the most. But I also have a man eating Stihl 051AV from the mid- 70's. It's got the 33" roller tip bar and I use it to slice up fallen oaks up to 5 ft. in diameter. I look at chainsaws like I do my firearms and credit cards. Use them if you need to, but give them respect.
