People hear GIANT and the automatically think "Seymoure".
Gian flytraps, Dingleys, and others, are giant because they can exceed 2 inches on their traps, I believe some have reached 3, but not much more...
Someday, I am sure, some little geneticists will make something bigger, and wholly inneficient... won't that be interesting...
The two most popular giant forms are Dingleys, and BigMouth.
I am not aware of anyone who currently has stock in them. (But I have not gone looking either!)
