I'll take a roll cage that transmits forces away from me over one that folds at the joints like a hinge any day of the week. Even if part of it
bends or kinks from an impact, if the rest is properly triangulated everywhere it will still prevent the cage folding and transmit force away from the
damaged area.
The most important parts to the tringulated are the rear bar and the rear stays. Which are both MSA standards anyway, nothing else really can be
triangulated anyway, not without obscuring vision or impeding entry/exit.

Perhaps, but the bends in your roof bars mean the front windscreen can fold down flat if it's hit longitudinally.
Also means if it has a gentle roll the leverage from the top bars will probably tweak the chassis into a banana shape.
Both of which I've seen happen with similar designs.

That said, the general sentiment regarding the 'normal' height of an MNR's roll-over protection still stands... they're feckin
huge and often spoil the looks of their cars!
Even at 6'8" his head should rest on the err! head rest. The height of that cage would indicate that the top of the head rest would be
about shoulder height, and the harness slots half way down his back! I think?

Yeah, I was wondering about that too.

Says the seller isn't 6'8" (that was the original owner) so maybe he changed the seats? Should have changed the cage at the same
time.

There not all infeasibly large! I have had comments that mine is to low, but I have 4" clearance above my head and the front cross bar does not
obscure my view, its perfect for me as it was made to measure. For the record I'm 5'11".

Certainly is, checking out his archive, no pics of him in it though.

No doubting it's a pretty car... despite the climbing frame perched on top!

That car was indeed built by me! And yes I am 6' 8" The cage was chosen to actually reduce the height of the rear rollover, as without it,
the rear rollover would've been roughly 4 inches higher to clear my head (in helmet) and meet the front edge of the engine. The heights were all
set by MNR to be safe as people have previously said.
However, I am totally in agreement with Scootz that the MNR cages do look huge, and in the case of my car, utterly massive. I hated it. But there
isn't much option for someone this tall. Same as the seats. The head rest barely met the bottom of my neck, and the harness was as long as
possible to go up and over my shoulders, but these are just sacrifices you make when you have to duck under most door frames. It was either that, or I
just didn't build it. Tom who bought the car from me was my opposite as far as build goes. Lovely bloke and I know he's looked after
it.

Not having a large roll over hoop was one of the reasons I went for a full cage - more safety being the primary reason.
I think mine is much more in proportion to the car - but I'm not 6' 8"

That looks spot on, much more proportionate.
