I was going to wait for the T5m but my lhs had a XFactory X60cf conversion for my t4.2 for $250.00 I have several t4 versions so converting one was a no brainer. I love the the way the mid motor handles, much better balance + its carbon chassis. I don't like aluminum chassis, one hit odd can tweak them just enough to make it impossible to get to handle requiring replacement. Had that issue with my t4 gt.
