Please help me choose an Espalier style for this space

Hello gardeners, 

I started growing an apple tree last year which I plan to train across the wall at the back of the garden.

When I originally planted it, I was intending for it to be roughly as wide as the wall, or there abouts. However since then, my plan for the layout of the garden has changed which means I'll be keeping it confined to a smaller part of the wall. The area to cover is now a bit more square. (2.5m wide and 1.8m high)

I'm not certain whether my original horizontal espalier plan will look as good with the new dimensions. The first tier arms are still flexible enough to alter the angle - it's not too late to rethink. So I've drawn up on the computer a few ideas to compare.

Please could you let me know which design you think would look best in this situation. Thank you. (Feel free to suggest other options - I picked these three because they fit the wiring on the wall and the shaping that I've already done with the tree.)

1) Horizontal Espalier
2) Palmette Oblique 
3) Palmette Verrier/Candelabra
