Apparently there are still a few lines left to try for Alex Megos in Frankenjura. At least there were a couple until recently, when he flashed an unnamed(?) 8b+ and climbed Baroness, 8c, first try.
I'm sure many of you are now thinking "hang on...what's the difference between flash and doing a route first go?".
In this particular case, the answer is that Alex rapelled over the route and brushed the holds prior to the ascent, hence no flash. Very few have flashed 8b+ or harder in Frankenjura.
