Traxxas Slash 4x4 2s/3s motor choices

Hello
Looking around trying to find info on what my motor choices would be when and hopefully before the traxxas motor goes leaving me with a Traxxas sensored ESC unless it goes to. Woulded mind running a sensored motor but doesn't matter. I'd like some options staying with 2s for now not sure what ROAR rules we be but on the indoor track that where running on I find 2s enough vary conpetitive. I also have a spare Mamba Max not the pro and CC Monster. So Motor choices please.
