I run a Dolmar 5100s 16" bar all the time. ( until I need a larger saw of course ) Before that I used 346xps and before that it was husky 42 specials. Actually, over the winter I picked up a 346xp new edition to see if it keeps up with the dolmar, I haven't even ran it yet but I do like the feel of the husky better & the slimmer profile. Ive been using them for topping saws for over 15 years, but I will sacrifice a little weight for the extra power and torque of the dolmar. We will find out Monday when I get back to work.
I tried top handle saws before but I just cant get used to the feel plus they lack power big time. ( 95% of my jobs are removals) It's funny watching some of my competitors doing removals with the top handles, in the time it takes them to make a cut, I'd make 3.
