g'day sandgroper,

any tool is only as good as the person using it, yes the very tip of the
nylon is what is designed to do the work once you learn usually by watching
what is happening as you work you will get adept at adjust for nylon wear as
you cut.

just to get the idea when next the machine is started work the head in
toward the material to be cut you will see when the tip is working. in all
cases i would not recommend tap-n-go heads, to me they take away the hands
on of the user and are very line wastefull, plus as they are designed to be
contacted with the ground they wear out and as they have moving parts they
are prone to failure, my policy as always in all things keep it simple.
