Big numbers don't make a difference when it comes to fear of falling, or rather of falling and hitting. In general I'd much rather pop off on a 20+ than something easier, not an ego thing at all, but in general the lower the grade the more likely you are to collect something on the way down/snag a rope/bounce off a ledge and hurt yourself. Not always true, but close enough.
The more you climb, big or small numbers the greater your confidence and when you have the confidence then fear is just something that helps keeps you on track and focused on what your are doing, but doesn't interfere with the climbing. |
