No, some clones are more vigorous than others.
Honestly, I'd just get my hands on a bunch of seedgrown typical flytraps. Usually cheaper and more natural. I have B-52...or what is supposed to be B-52, and "SW Giant" performed much better...and it has much longer leaves. I once had a 'Royal Red' and found it to be rather slow-growing and hard to please.
