Sorry, been busy instructing the other half on a gooseberry crumble.
The reason I asked for the pic was to see the tips. The pic I have in THE BOOK, has small bobbles on the ends of the tips where as giant palythoas don't, the colouring seems to better fit the palythoas too but as you both say, a bit like flipping a coin.
May have to wait for Ski, I am sure he has some giant paly's in that colour or similar, he may be able to rule them in or out.
