Here a picture of the Boa, a boulder problem I opened in Switzerland this year.
It is a sit down start on a big snake like looking structure, which also gives the name to the problem. Some powerful moves on pockets underclings that bring you to a tricky traverse with more pockets and a finish with long moves into a big flake. It ends in another problem called “Mosaik”. The first four moves are by far the hardest, but the last ten are quite delicate and bring a great dimension to the line. You can see the start of it at the end of the movie by Bernardo Gimenez: http://www.prana.com/blog/tag/fred-nicole/
