I'm leaning towards the re-71r (don't expect more than 10k out of them). Most normal tyre shops can get them but won't stock them and they seem to be only a little more than the re003. Gordon leven in Sydney seem to keep the common sizes in stock (they only do motor sport tyres) tyres shops have referred me to them before as apparently they get priority over jax/Bob Jane etc on the high grip/short life tyres if you need sizes that aren't commonly brought into the country in qty.
