Hey sunny...sorry it's taken so long to get back to you. I would buy plain bore pulleys and then invest in a hex broach and use hex shaft. Once you go hex you'll never go back. We refuse to use keyed shaft unless it's the only option.

Your comment about having issues with 25 chain is not a good sign for belts though. If anything belts require more precision than 25 chain. We need to sit down and look at your drivetrain sometime and see where the issues are coming from. Until you can run 25 without breaking it or having it come off the sprocket stay far far away from belt. Honestly there's nothing wrong with sticking with 25. I am still debating what we will do in the future. I love belt but I like a lot of aspects of chain as well.
