We've run Optimas for years. They work great. I currently have a yellow-top in the Kick, and have done a few things like leave the radio on for a really long time while I am working around it, or leave the dome light on all day. Still starts and runs like a champ. Plus all my radio (sing song and chit chat) gear doesn't bog anything down.
We've had them in past rigs with pretty big stereo setups, and go-go juice for the CBs, and they never fail us, and never leave us stranded.
Optimas are worth the money.
