I usually buy swivels,beads,bait clips,quick releases.Last couple of times i have bought Stren Blood Red line and found it quite good.Have bought a spool of cheap Powerstorm 20lb just to see how it compares to the Stren. I also like to have both UK leads and DCA leads in my bag.Hooks and shockleader are usually Sakuma.
Lunar products seem to have a canny range of terminal tackle and at very reasonable prices and they do them in bulk packs.
