I have literally hundreds of EXPENSIVE certified uv resistant cable ties
on my messengers to the towers.  The older ones are black and some of the
newer ones are blue.  I don't have enough experience with the blue ones,
but even the $1/each black T&B ties are only good for 8-10 years here.  I
am now protecting cable ties with several wraps of Scotch 88, with the
last wrap applied WITHOUT TENSION so it won't unwrap and make "flags" 
that flap in the wind.  Scotch 88 (and 33) seems to last forever. 

My suggestion: if you need a cable tie for strength you can't get with 
tape, use a cheapie cable tie of any color and protect it from uv with 
Scotch 88.
