Roll-over hoop, braced or unbraced?

[aerosam]

Hi guys,

I recently installed the roll-over hoop onto my chassis (welded rather than bolted on) and I'm wondering if there is much benefit from bracing it to the rear. Just having a quick flick throught the classifieds it struck me that most of the major manufacturers don't use any. Dax, pilgrim, wesfield, tiger, sylva, vidicator, mk, none i saw had braced hoops.

It looks good without them and unless it would seriously compromise the strength of the chassis I'd like to leave them out.
