7x7x7 blindfolded

Memorization time ~1.5 hours, execution time ~40 min. Memorization methods: visual for corners and RR for others. Execution methods: U2 comms centers, advamced r2/M2 wings/edges, 3cycles edges. First attempt was at spring, cube was completely scrambled //-_- Then I made reluctant break for about 3 mounths... Yesterday was second attempt (missed 3 wings) and today the fortune smiled on me (except F2 penalty xD). Still not a hardcore, but close.
