I know from my own experience that my RC8Te (with some upgrades) is holding up pretty darn well (no breakage so far), and the worst stuff isn't even in the clips.
But I'm reading that the Mugen should be even thougher so from were I'm standing it looks like a win-win choice :)
ps. Will you have one of the before mentioned truggy together with your 8T 2.0 or will it replace the 8T 2.0?
