I came across this on-line spear fishing store on eBay recently. They sell the sort of things that that can be hard to find: 1.9mm Dyneema, bulk rubber in various sizes, pre-tied bulk rubber loops with wishbones, crimps, etc..
eBay Store - Spearit-Company: 9 16 14mm, SHOCKCORDS LINE, 5 8 16mm
Based out of Florida, USA but UK shipping is reasonable.
Warning: you might find yourself paying import duty if your total order comes in a single package with a value much over £18/$35-ish (excluding shipping).
