I have two Yellow tops in my 4x4 have had no problem with them. Don't buy red tops they suck once you discharge them they are history. Don't know to much about the blues but they should be good. I also like the Exide spiral if you can find one, had one in my Dakota for almost 8 yrs. worked great. Oh one more thing if you get an Optima get it from Amazon got my yellows there for $156 ea.
