Thanks for the responses. I was eyeballing the F10s. Marker markets it as a touring binding, which is why I had reservations. For the life of me I couldn't figure out what the real difference was, other than more plastic. It is interesting to have someone compare them to the Squires, which is what I would put her on if I were to go with a regular binding. My wife uses the Squire. It is wicked light (compared to my Griffon) and has held up fine.
