Hi everyone! thought i'd post that i'd finally got results with catching my pony. I found he thinks it's just a game, so whenever he moved away whe i tried to touch him, i sent him away with my hands. It took him a few times until he worked it out that if he tried to move, he got sent away from me, and i made him move around the paddock.
Now- i can catch him without food or treats in a big paddock with other horses. Although, he will always move away when approached, i make him move, and then he stands still. The idea that 'if i run away i will have to do more work' seems to run true for him, and he seems to grasp the idea pretty well.

It's going so well that now my friends can go into the paddock and catch him easily. Thanks for all the ideas- and hopefully if someone else is having troubles, this might help them out.
