yeah you'll know when you get one, it will be more than twice the size of any other flower that comes up!
You can see the difference in size in this photo. That sort is more rare, it had its own stalk and little flowers grew out of the base of the mega bloom. Most other regular fused blooms are on a stalk shared with other regular flowers, but you'll still be able to see the difference. You can still get a bloody big tomato out of a regular fused bloom, but one of those mega mega blooms with its own stalk might get you a world record.
This is the tomato I have growing now, its not from that flower above, this is on my outdoor hydroponic plant, the one with good genetics, but I dont know the actual history.
