I own both QUIS and RHT. At present, I am even on QUIS but have a loss with RHT. If you were to own one of these, which would it be? I was thinking of selling RHT and adding to my QUIS position.

Neither is perfect, but QUIS is so much cheaper and we would side with it. RHT largely remains a 'show me' story, which it has been now for some time. (5iResearch)
