Sorry Dave ... just haven't got my head round the existence of the new-fangled aluminium ones!
My comment refered to all the trads out there.
If no-one has yet come up with a roll hoop for them it surely won't be long ... as for the 'oldies', Librands do them as do Safety Devices (well known in the racing world ... have a full SD cage in my MG) .... worth asking or they might put you on to someone.
