I also have two types, the normal shortcake which tbh doesn't do a lot, put out lots of new white tips but not a lot more, it did start to develop the green but I moved it because it looked stupid where it was that was about 2 months ago and it's just a brick pink sort of colour, but has great pe.
The other bit grows very fast, it's probably doubled in size since I got it 5 or so months back, it must have grown 4" across x 3" high x 4" of seriously dense growt of literally dozens and dozens of new tip growths. Since I added the ati hybrid it's developed the pink coralites but the main body is sort of grey in colour.
