I dunno, Dan. There are thousands of things in life it makes sense to save a
few dollars on, but I don't think fall protection should be one of them. If
you aren't willing to use a double lanyard or two gorilla hooks to keep
yourself clipped to the tower at ALL times (actually, a very inexpensive way
to go), then the commercial cable FPS with a one-way sliding ratchet
mechanism, clipped CLOSE to your fall harness, seems to me to be the right
way. Besides, a dead fall (no pun intended) of 10' plus lanyard length will
accelerate your bod to a very unforgiving stop, likely slapping you upside
the head or body with several thousand pounds of tower. Recovering from a
fall and climbing back down with a broken arm or shoulder might not be much
fun, either. Having to unclip/reclip every 10' would give me the willies,
but then I'm basically old and chicken where towers are concerned. Being
unattached at ANY time is something I just won't do, it momentarily reduces
my mental comfort level to near zero. I seem to recall something about there
being no old, bold pilots... :-) I wish you brave young fellers out there
the best of luck.
