A two year warranty on a string is amazing to me. I won't shoot a string that long--I swap out every 6-12 months, and that is on a longbow.
I like the 8190--it should be more durable than the 452, but may have a touch more stretch/creep--but again, I only shoot traditional bows.
Chad; I'm with you. I change strings out so much two to three times on compound bow because of the tournaments I shoot and I perfer 452, and 8190 on my long bows.
