Nearly forty years after the first ascent of Endo, the low start has gone down. Sit start low on the huge jug below the arrow blaze. Crouch traverse to the right and do some funky moves to stand up into Endo's starting undercling and then finish it up.
The sit adds five additional moves, three of which are beta-intensive and one of which is quite unexpectedly stout. Prepare yourself; your range of motion will be tested.
This problem is the sit start of Endo, which is the left-most line of the Left End.
Pad and spotter; blowing the mantle would lead to certain unpleasantry.
