Phew! thanks for all that info! I have to say, I've tried most of those, and the last option was going to be to dunk the heads in a pan of boiling water to get them all off. Unfortunately, broccoli is very good at repelling water, and little air pockets keep the blighters safe from drowning in amongst the flower buds.
Oh well, I did get a fair bit before these fellas took hold, so the last little bit wasted, I'll just have to put up with! And, my calabrese from last year has produced wee mini florets almost continuously since last summer!
I suppose you can't have everything .....
