The Jonsred is a good little saw shares a lot of parts as the husky, and if your logging all day the husky and jonsred are a bit lighter than the sthil, trick we used to do was to get a resonable power saw and drop it to the smallest bar and chain you could get to increase the cut speed, remember if you puttto sharp an angle on the chain teeth you will cut like hell but u will spend most of the day resharpening, likewise not enough slow cut rate, when i did my licence they reackoned ideal was 32/36 deg was about right...
