Bizarre beta: inside flag
The inside flag, when correctly applied, can make a sequence much more secure compared to the alternatives, yet it is one of the techniques that are rarely seen outdoors . It's not especially hard to perform it - I would say it's much easier than a foot swap, which is usually the other option for doing the same move. Therefore, the infrequent occurrence of the inside flag in the beta of rock climbers might be due to the confusion about when to use it and what can we gain with it. Additionally, it's relatively uncommon to find a situation where an inside flag is really the best solution, but when it is, it might make a move easier or, which is usually the case, less low-percentage.
