Thanks for the sharing coach Bob. Since I'm trying to learn the start, I was curious about the new blocks: do you mean the ones which aid the track start (ie one foot behind)? Are these blocks so different from the old ones to the point of affecting your dive?
Another question: have you ever dealt with goggles problems after the start? My main concern is leakage: in a short event no problem, but on a 400m and up I wouldn't like to have to stop, clear the goggles and start again.
Currently I'm practicing some dives from the side and goggles usually stay in place (sometimes they leak when I don't tuck the chin enough). I'm not that confident though, I'm still quite scared of diving from the blocks. I tried once and the goggles leaked badly.
