If you want pulleys for your flysurfers then I can recommend the ronstan pulleys for both the pulleys on red and green lines or on the depower. I have been using them for 4 years on Maniac 5m and Warrior 7 and 9.3 and they generally work well so long as you keep them reasonably sand free. You can get them at Sailpower in Carrington St in Nedlands.
Riley make very small pulleys. Not sure who stocks Riley accessories on the North Shore, but you could try ringing places like McKay Marine in the south, they stock it for sure.
Have a Wipika pulley bar with a Ronstan pulley, The bearings are ceramic and have barely lasted a year, recon stainless bearings might be a better bet....The pully's ain't cheap
Oh yeah, you can get pully's from Bluewater fishing tackle shops all over the metro area, there's one in Scarbs, not sure of the quality, but price friendly I bet.
