g'day rob,
i live near brisbane queensland, and while we don't suffer frosts like others even here in australia we do get them one reason why we like living in sub-tropical east coast climates our biggest contender is long hot dry summers, it was the black frost that did the most damage.
yes i let the first heads grow as big as they want to i pick them as soon as the tops start feeling loose, i have harvested upo to 8 picks from my broccolli, most second onward picks are no bigger than fist size and anything smaller than that, i use it all the same way as the first picks like eating broccolli in lots of ways. also always get to share a lot of broccolli. the biggest one wa around 11"s across the widest part.
