In reply to wildbill: in the respect of drying holds, generaly while bouldering, using towel, beer towels and tissue to get rid of most of the moisture/damp/wetnes. if using chalk after this u will probably need to chalk then brush of and repeat process untill useable. i have much experience in trying to dry holds, ha ha.
using a bucket load is pretty...well...stupid and hard to get rid of. it will also take holds longer to dry when left in comparison to bare rock. in my opinion less chalk is more acceptable... like standard climbing
