Cheferson,
Technically, the original Vivif was the first rubber, paddle tail bait with a molded in weight. Panther Martin likely purchased the name.
I used them back in the 60's and caught the hell out of the bass in freshwater.
Here are the originals:

I have some of the newer ones as well and it would appear they (storm, vivif etc.) are made in the same factory.
I do like the Vivif color selection as well.
