Ascension de Zehnte Sinfonie comme Working

Thrutchy, unspectacular 6b/+ climbing up some tufas to a no-hands sit down rest before a bloody fantastic crux sequence on the thin tufa fin into a hand crack before rounding left into a techy slab portion (6b/+). Crux boulder through hand crack is about V3/4? Route is rated a 7a in the guidebook but seriously it's either damn stingy or the hardest 7a in Thakhek! One-hanged on my 4th attempt but ran out of time this trip. Will be back to send!
