i've got two questions... 1. can i replace my existing 4 strands (on wooden and t-posts) with high tensile? i want a heavier gauge (ie. hopefully less breakage and maintenence) than the 15 and 17 in use now. i mean, can high tensile also be electric?? 2. i know there is a way to put wire around the goats neck and dangling in front so they get a harder shock, but cannot remember the details. anyone?? it's spring. seems like they are worse about getting out in spring and fall. so, thanks!
