Optima Red vs. Yellow

[muddpile]

Since I had to buy a new inner fender, front fender, battery tray and rebuild my rad support due to rust, I have decided a sealed battery is the ticket for me. I have read countless reviews on here, and Optimas look like a good deal. One thing I can't seem to see though, is what is the better choice, the yellow or the red? The yellow looks like it can be drained/charged a million times, but what are the advantages to the red? The color means nothing to me, as I will be painting the top to match my truck.

Also, what do I have to buy for adapters to get this thing to fit my factory 72 battery tray and hold-down?

Thanks!
