[TowerTalk] Pre-Stretching / Anticipating Stretching of Antenna Wire

[Steve Sacco NN4X]

I'm about to begin building a wire antenna for 80 meters.  I'll be using 
14ga stranded copper wire.  Since it will doubtless stretch once in 
service, I'm wondering if I shouldn't try to either pre-stretch it, or 
build it a bit short, to allow it to stretch into its proper dimension.

Anyone have any experience with either?
