Does anyone have any beta for the section on the upper wall of Bat Route where you go between two sets of undercuts? I get too stretched out if I go directly undercut to undercut so I need to find another way. I was told you take a left hand thin side pull with a thumb catch and step through with your right foot to reach up but I can't get this to work. The only way I have done it is by crimping the top edge (the thumb catch) of this thin side pull and going up with my right hand but I suspect this might be hard on the link. Any suggestions welcome!
