"Spannungsprüfer Variation"

A few weeks ago I climbed the straight line through the roof called 'Spannungsprüfer' which was established by Markus Bock already in 1999. A friend then told me that there's another nice boulder that climbes from the left into Spannungsprüfer and is ~ fb 8B. He didn't know it's name and I couldn't find it out until today, but it's a nice climb and it doesn't matter how it's called in the end. Last sunday I went there to try it. First it felt impossible but I could find a nice beta which made it doable. On that day I was to tired from checking the moves, but yesterday I could execute it luckily, although the conditions where less than perfect.
