two braids that work for the leader
a) Gardner 22lb Hydrosink - 0.35mm dia
b) Korda 20lb Sub braid - 0.36mm dia
i no longer use scissors to cut braid - bought a Berkely braid cutter tool - basically a battery operated 'hot wire' cutter which fuses the cut so no fraying
also for components have a look at Bank Tackle - cheap and quick delivery
i have no association with Bank Tackle
also another great Berkely tool - the battery operated line stripper - great for hassle free stripping old line off spools
