Flubromazolam and clonazolam are nasty drugs to be avoided at all costs in my opinion.
Etiz has a shorter halflife, so you are far less likely to black out for days/weeks/months at at time, compared to c-lam or f-lam.
If you do a seach in the BL search engine, you'll see plenty of horror stories. Personally, i had a massive trainwreck on flubromazolam and absolutely detest the stuff - it almost ruined/ended my life.
I'd really advise staying away from them, simply because they cause such terrible amnesia/tolerance/potential addiction.
