I am somewhat amazed, but very happy to hear
that some testing seems to show that the heat issue...

...is a non issue

I think Billy summed it up..something in-between the Trooper bare bones approach
( which does seem to work perfectly well when lifted) and the full Kilby sheathing would be the ideal set up.

And yes Sue, I think your standard ride height probably benefits from the full coverage ,
however other non lifted VX's ( Mr G !!) do gnarly trails without ...

In most cases,I would spend the money on a lift FIRST .

Of course a good spotter helps more than anything!
