My hesitation in buying the safety cable was simply that I didn't want 
to trust my life to a spring gripping system I suspected I wouldn't be 
able to see (I've never seen one in person so I wasn't certain how 
enclosed the mechanism was).  At least with the gorilla hooks, I can see 
that they are closed and that the safety latch has been been locked in 
place each time.

The gorilla hooks release and open all in the same hand gripping motion, 
so it is not appreciably slower than simply climbing or descending.

In addition, I can use the two hooks and safety straps to climb around 
the tower and suspend myself wherever I might need to work so that both 
hands are free.  That wouldn't be as workable with the safety cable 
unless I brought along extra straps anyway.
