Good write-up Andrew. Your weights are almost identical to mine, so the build is definitely consistent, although I have not really had much in the way of leakage with the Blockleys. My first pair were slightly worse in that regard than the current two, but it was very simply fixed with a 3 second blast of tyre-weld in each wheel, followed by a short warming drive - never budged after that. Haven't had to bother doing that to the current pair, as they hold better (I still check them every 2 weeks or so).
