In reply to Adamevans:
In my opinion, the edelrid bucket has by far the best closure system in terms of Zero leakage of anything which is a definite bonus, however it doesn't have as big an opening as some of the others.
The metolius bag is the best in terms of side and shape and has the perfect pocket on, however has quite a lot of leakage..this leaking of chalk is pretty common with most drawstring buckets though..
