I tried Rohypnol (flunitrazepam) when Roche used to make the pills white and small (1 mg). I took them sublingually. It was in 1999, and I must say it was nothing special. They really looked like the Roche Rivotril (clonazepam) pills you can find today, white, small and a good minty taste. Now the Roche Rohypnol pills are big, blue and green inside (if I remember correctly, to prevent them to be used as a "date rape" drug). As I said, if I had a Rohypnol pill as Roche used to make them before and a Rivotril pill in front of me, and it had no imprint or score on them, I really could not tell which pill is what. I even think that mg for mg both Rivotril and Rohypnol are the same potency. So, really, apart from its reputation, Rohypnol is nothing special. Stick to clonazepam, it must be much cheaper too.
