I figure I'll share my color neutral transition story:
It was November 2013, and I averaged 25 seconds. I went on vacation for a week, so I couldn't time myself, and I thought, "I'll try color neutral solving for the week, and see what my times are when I get back." I jumped straight into color neutral, solving on every cross color (except my original color, green) right from the beginning. When I got back, I did a 27 second color neutral ao100, within a month I was faster than my old times, and now I'm sub-15. I don't know whether or not I would have made those improvements if I hadn't switched, but I certainly don't regret switching at all.
