Paul, simple answer - get modern and don't wear knickers!
Or, do away with the "bobbles". I have a figure of 8 loop tied into the rope going through the pole. The knot on it is large enough to stop the rope end disappearing into said pole. This is NEVER undone. The bit of string used to tie the jib sheets to the jib clew goes through the loop when it is tied on so it attaches the pole at the same time. I have yet to get my knickers in a twist with this set-up.
