Well, risking alienation here. HBRN chose the wrong thread and method to go dissing port work,, however. Not all good loggers port their saws, and not everyone that ports their saw is a good logger. This forum does lean to the 'ToolTown' mentality of hopping up whatever runs, and many do it well. However, time saved in the workplace is all about working hard, working smart, and having the right tool for the job. The right tool for some may well be a stocker saw. And the need for ultimate horsepower by the occasional sawyer..is dubious. Some of my saws are ported, and I'm glad for it; but I know some stand up loggers that wouldn't bother with port work. These are folks I hold in pretty high regard, and make their living in the woods.
The motivation for hopping up saws are many, and all of them just. It does not however make you wise, and to choose not to does not make you a fool.
