Training grape vines up a brick wall?

I've started doing this by using lag shields and eye bolts . What do I do with the shorter vines that are growing "away" from the wall? Do I wait till they get longer and curve them towards the wall? Or just prune them?

Thanks!

It really depends on how big the vine is and what you want to do with it .
If you are after grapes then prune .

David thanks for the response. I am primarily growing it for grapes I'd say, unless there are other uses for it that I haven't learned about yet. The vines are maybe 3-4 ft at the longest right now.

For grape production you need to prune it anyway. Maybe you can fix horizontal wood frames with bolt and you can fix the bearing vines etc.
