(10)

Start standing, matched on a good edge system left of the blocky feature. Climb straight up to a slot, or a sloping edge, match and jump to the jug lip. This can be started from Blocks Sit, making a more complete line and solidifying the V10 grade. A classic.

another from yesterday in Wild Basin. 25 attempts (,: basically a TB2 climb outside. the low doesn’t really add much imo, just a v3/4 traverse into the meat of the problem. taking soft v10. i usually do things in 6 or less attempts.
