Personally I enjoy the rigging aspects of modelling almost more than the construction part of a build.
At least with deadeye lanyards and ratlines we are working outside of the ship, and time consuming as those jobs are there is a great sense of satisfaction to see nicely rattled down shrouds, and neatly set up deadeyes.
My own pet hate is the belaying of the Topsail and above running rigging lines, such as the bunts, leech, bowlines, and halliards. Invariably by this stage there is already a lot of rigging in place and the opportunities for snagging given a momentary lapse in concentration seem endless.
The stropping of the smaller rigging blocks also presents a level of tedium I could well do without.
