Go electric shifter, this way there is no CO2 to worry about running out. LOL dont hate on automated shifters. I always said I would never run one, then I joined the top bulb class and the window got even tighter to turn on the win light.
If I ran a class like that I'd probably want to win too, if that's what it takes. I was really just making fun of the glide with automated shifter (pop up toaster)
