I wrote a training article with John a couple (?) of years back for Gravity. There was some nice shots in that if you can find a copy, aswell as a brief insight into what Mr G did over the years to get so strong (originally a runner, as he is again now).
I've just read on UKC that John may have repeated Kaizen after the demise of the footblock that I displaced (bugger). I'm not sure about this, but when I was interviewing/chugging wine at Chateau Le G, we were discussing the grades of his 1st ascent tick list. John reckoned Kaizen was entry level V14 with the block, but had done the majority of the problem without this (a fair while ago). He thought this was probably top end V14. Get back on the Trowbarrow poject goddam it!
