A friend of mine has some circuits on his board (with named holds) that were too long to memorise so he recorded himself dictating the circuit, then climbs with an mp3 player on: "left hand orange 53" etc.
No, Mr Bond, I expect you to smear
The chalk wont last long either so whats the best system for me to mark up the circuits for reference as well as clocking the right holds whilst climbing which is flexible to adapt when adding or subtracting holds to make it harder/easier? :or something else...?
We name holds in the mill then for circuits we use tape. You can even write left and right on the tape with a permanent marker. Obviously use different colours for different circuits.
That sounds best
