If you manage Kopiščarjeva before, then you shall not have any big difficulties continuing to the top. The ridge is badly secured but far from being very thin, comparing for example with Triglav's one which is but very good secured!
You descend by 'Slovenska' or back by the ridge to the natural window when Kopiščarjeva joins the normal way which you use for descending back to Vršič pass.
Be carefull when driving up to the Vršič pass, if you come by car. Cows on this road, left by careless farmers are very frequent and they are general Slovene way to give you adrenaline on mountain roads before you even start the ascent
