but to you, does Jared or Jensen have the more apparent accent?

Very good question. Actually, I never noticed an definite Texas accent from neither. But then I'm no native speaker, and my knowledge on US accents is even worse than my knowledge on British accents :-) Someone once pointed out Jared has more of a "twang" when he talks which is true I think, but as to the rest? NO idea. I think I'd only notice their accent if they talked like Bush. I live in blissful ignorance :-p
