I am going to a single ring 34t up front. Can I get away with keeping my long gauge rear mech or do I have to change it?

    You can keep it.

    You can indeed. Or run medium, or run short.

    I find the tension is better with short on a single up front and I get a lot less chain slap. Some run chain devices instead, or as well.

    Try it with the long and see how it goes.

    If you shorten the chain sufficiently you won't get any more chain slap than you would with a short cage mech. The only benefit is a slightly lighter mech and slightly less chance of smacking it into a rock
