LK is right on the money. Also factor this, on day #1 I work pretty fast off a 12 foot step ladder. On day #2 I start out slightly slower and by the end of the day am begining to feel it. On day #3 marked difference in speed. All this is negated however if the job runs 2 weeks or more in which case I get acclimated to the weight of moving that ladder around and it all becomes normal again. Make the job last 6 months or more and I can work that ladder like its a 4 footer.
