    Depth is an issue with the simple, quick, and easy-to-use installation

my club does.  The greater the distance, the longer the wire, the more
that 
wire flexes.  IIRC, the Tortoise instructions say to use a 1/4" hole.  Ha!

The wire flexes when it's thrown all the way over.  If the bending wire 
touches the sides of the hole during the throw, the point will actually go

all the way over, then come away from the stock rail at the end of the 
throw.  This is not good.
    If we have extreme subroadbed depths (exceeding 1 1/2"), then we not 
only drill a 1/2" hole through the roadbed, we also drill a 1" hole from 
underneath to give the wire more room to flex.  FYI, I think we've only
ever 
done this twice (out of hundreds of installations).

    I did that once.  It was enough.  All other holes are drilled down
from 
the top.
