we thought about co-axial but we dont really have the machining tools to do it(or the experience) and we assumed it would be alot heavier(i dont know about this)
The belt will work just fine for steering, my team used it this year and it worked fine. Just becareful though, if it slips, it can totally mess up you feedback sensors. My team found that you need a little more wrap around you sprockets with chain than you do with belt. My team also needed a spring tensioner to keep proper tension, but it these aren't really big problems.

Non-Coaxial isn't really much heavier than co-axial, the only thing is co-axial is typically much less efficient. So I'd say noncoax is a good call.
