Hi Tim,
We dont have much discussions on here, are you on Facebook? If so check out the Australian XRAY Page:

The XB8 will be similar to the MBX6, couple of major differences will be more steering while being stable and easy to driver but a LOT stronger all round. You wont break amuch at all if anything!! It doesnt wear out as fast either.
Maybe ask the same question on the Facebook page and im sure you will get more people posting : )
