Hey rosti, welcome to ATP. It really helps more if you can give us at least your city and state. Your zone only really tells us how cold winter generally gets on average. A zone 6a in Utah (high and dry) is a very different climate to zone 6a in Missouri or Maryland (low and humid) or Oregon. Different plants will survive in different areas.
There is a space in your profile page to put in your location, and then it will come up automatically any time you post.
What kind of support are your vines going to be climbing on? Clematis does well on chain link fencing or anything with small supports to wrap its tendrils around. But a plank or picket fence might not give it enough purchase. Honeysuckle likes to twine around vertical supports, so again, they can't be too big.
Also are there any trees upwind of your property that might provide a windbreak at least in the warm months when they have leaves? If not, you could think about planting some! A berm with small evergreens can also deflect a lot of wind to help your garden get established.
