Currently this is in at 9a but recent ascentionists seem to have found much better sequences on jams than the sequence used on early ascents. By the grade suggestions a downgrade would not be in line with the style guide https://climbing-history.org/tools/style#terminology-naming-and-grades-grades-choosing-and-changing-grades, but this feels like slightly exceptional circumstances where there's been a significant improvement in beta so it seems like grade suggestions from earlier ascentionists should have less weight.
Legendary crack wad and notorious sandbagger finds morpho-jam route only very hard. I'd leave it for now!
Ha, point taken!
