Now I've taken old tape off towers and found bright shiny zinc 
underneath.  I suppose that's where the YMMV comes in!  Anyway, thanks 
for mentioning that. It may be that in certain environments (perhaps 
acid rain?) tape can promote corrosion, (e.g. by holding moisture 
against the tower) while in others it inhibits it.  It's good to take 
that into account.  Of course it's always a good idea to prefer the 
better solution, even though it may be more expensive.  I've seen cables 
mounted with stainless steel hardware and no problems for the life of 
the tower, and that's probably your best solution if you can do it.
