Max height in accordance with BS EN 12572 is 4.5m. I think our highest bit is 4.2m in main Works although I think we hit 4.5m in Unit E.
What's your thought on this with the change in walls using ever bigger volumes and Kilter style dongs? Minimum mat extents with walls (specifically slabs) doesn't seem sufficient.
It's also interesting regarding the IFSC rule about setting. I don't often watch the Bouldering World Cups but have there been many/any external fractures? Plenty of the walls I frequent seem pretty happy setting big last moves, often with feet quite high which I now simply won't do (
).
