Eddie,
I'm not sure you need to truly buy high tensile fence, but rather run a high tensile wire above what ever fence you install. Run that top wire with a spring and tensioner and you should be fine. That's what I do with my fence. I actually ran 48" tall 2" x 4" woven wire fence with a high tensile 12.5ga. twisted smooth strand at the bottom that I hog ring the fence to , this keeps animals from pushing under it, I run a second high tensile 12.5 ga smooth twisted wire at the fence top that I hog ring the top of the fence to and then I run a third high tensile 12.5ga smooth twisted 2-3 " above that. If I need a hot wire, I can use the insulated t-pole standoffs between the second and third wire at the top of the fence.
