My original plan was to go with the yellow. (yellow is faster) The roller I ended up with is (and originally was) Zambezi Green. I can't afford an acid dip or sandblasting (the "right" way to do a color change). My thinking was to do it anyways, the best I could. I plan to paint it in my garage.
Recently though, I find that the Zambezi green is growing on me. I don't like it as much as the yellow, but I like it alot more than I did at first. This leads me to the dilemma of what to do.
