How much are you looking to spend on each? Are you willing to grind your rim? Or keep it smooth? I'd say Plaz CRMs for a grind, mine have lasted aaaages! Over a year I think, they started wearing, then just...stopped. - £17 from Tartybikes. Zoo pads for a smooth rim, maybe with a bit of tar. - £18 from Tartybikes I was riding with Sam Wheeler yesterday, and he had Zoo pads on a smooth Viz rim, made a very load noise, and locked really well! For the booster, either the £20 Echo one as mentioned, Echo Team 2 bolt, Echo Control 4 bolt, or Heatsink. All good boosters. There are plenty more, but they're the main ones I can think of right now. One thing about my booster (Echo Team): When I stripped the threads in my brake mounts, I took it to a local engineer, and he looked at my booster spacers and they were callapsed. "Cheapo aluminium shite" is what he called them. So he made me some stainless steel ones! And they work really well, and wont collapse like the Alu ones. If you can, get that done from a local engineer. Cost me £20 for him to helicoil all 4 mount threads, stainless steel booster spacers, machined out my mounts so the spacers fit, and to clean the holes, and gave me some steel bolts. Oh, and he drilled out a rounded bolt!
