Has anyone else bought any of these, I did in 1/8 oz and 3/16 oz and while I like them they do not seem to be as good as the tru-tungsten brand, but I do not own any of the tru-tungsten in weights this light so it might be my imagination?

I have them...  some subtle differences, maybe but you get that in any brand comparison.

One day I sat down and divided out the cost per weight in several sizes and brands...  the conquistador was the better price/unit in most sizes.
