Skin preservation is an issue for climbers of all levels. Webbo does have a point. It might be worth having a backup plan for the final day e.g. a nice walk and pub lunch.
Glad to hear you are planning some "real rock" James, but why you heading all the way to Caley? Don't get me wrong, it's a fantastic spot, but unless you have another reason to be in the area, it's at least another hour further than anything in the Peak District, plus you have to negotiate Leeds, which can be tricky on first acquaintance. Otherwise, other's advice is good - skin management is key, and expect to get spanked (by the rock that is, no idea what your evening plans are).
