One of the things that i currently suck at amongst many others is hand/finger jamming.
None of the local walls near me have these new wideboyz crack volumes ive seen popping up from what i can see so i reckon good old outdoor bouldering will be the way to go.
Anyone know of a location with good crack/jamming boulder problems. Ideally N Wales, Peak District, Lakes or North West in general, even a grimy Lancashire quarry
