Optima is made in Mexico but they do not suck. I think they went through a rough patch when they moved production but that was a really long time ago.

Dom I would use one yellow top, two if you need the ballast. I have a single Yellow top that is seven years old and it is working great. I have electric WP, Two Fuel pumps, two fans, and EFI. I have made as many as twelve passes at the track cooling it down between rounds with zero starting issues.

You can also use the blue top with the light grey bottom. The Blue tops are the same thing they just have the marine terminals on them and no side posts. The Blue top with the black bottom is the same as the red top. The downside of buying the blue tops is that the warranty is only two years vs three for the yellows and reds.
