I had one on my Kingpin, and I almost got rid of it. I got used to it, however, and kept it. When I traded it for my VV I thought I might get a heel toe shifter, but I found I like not having the heel shifter behind my boot. It gives more room so I never changed over. So I guess I am indifferent. When I had one I was okay with it and I am okay without it.
