Wire fence on a slope is tricky. For stability, the rule for wire fence is that you need a brace to pull from and set wire to, every time the fence either 1). changes direction -and/or- 2). the slope (and fence) changes pitch. If your pitch changes 3 times in a 14 foot fence run you will need 3 separate braced sections of fence. Some small bumps and holes can be mitigated through a bit of regrading of soil.
Run a single panel for each section where the pitch of the slope is constant. Where the slope pitch changes you will have to set another sturdy wood post or post brace to pull the next section from until the pitch changes again. Set your posts vertical with added height for adjustment of the slope. Align your fence with the bottom wire level with the ground. Stretch fence and set it bottom to top. Where you have to cut the panel to adjust to a new pitch or attach to a new post brace, do so leaving the vertical wires intact. Do this by stair stepping the cuts in the fence. Your ends will be much easier to work with this way and won't compromise the fence stability. You can then wrap the extra bit onto the post brace if you like and attach with staples.
I hope this makes sense. It won't look perfect but it is agricultural fence and isn't meant to.
