Why does it ring a bell in my head that telephone poles are a No-no for using as stand sites?..........safety, legaility? Heck I can't remember.[&o]

If there isn't an issue with actually using the poles, 10ft is OK as long as you have sufficient back cover, and proper wind direction.......and some unpressured deer. You definitely don't want to look like a loli-pop.
There's places I've hunted where if you tried to hunt 10ft up in an exposed telephone pole all you'd be able to hear are the deer laughing well before you didn't see them.

Also try to chose a specific stand where the deer's primary travel route doesn't angle toward your stand at all. Don't give em' an excuse to simply raise their heads....and laugh.[8D]
