Recently, the more popular variation to Americana Exotica starting matched on underclings slightly to the left near the vertical seam. Move up and left through underclings to reach the jug midway up the wall. Trend right to topout through the suspect flakes the same as Americana Exotica.
The left variation that this climb has slowly morphed into just seems to be the optimal way to climb this face. I do think it is distinct from the original line since the start position is different and the difficult holds used are different. For me, the left felt more V9 than V10. The right pinch way felt very hard.
