Polish climber Alexandra "Ola" Taistra has repeated Mind Control and Fish Eye, both ~8c, at Oliana, Spain?
On her blog she writes about how different the two routes are to each other, even though they are on the same crag.
In short Fish eye has a little if everything, while Mind control is more of an endurance route on mostly small holds. Originally given 8c+, most now call Mind control ~8c. Alexandra agrees and says it's probably hard 8c or 8c/+.
Last year, Alexandra climbed Cosi fan Tutte, 8c+, at Rodellar, her hardest route so far.
