I used to use the Gliding Federation logbook to log all my hours and then a conventional logbook when I moved into powered flying. I don't think it really matters anymore, there used to be stipulations on gliding time only counting for
50% powered logged time if i recall, but think it changed later when the legislation was updated?
Never got to experience winch launches, only aerotow where I flew, but yes gliding is awesome and is a fantastic way to learn solid stick and rudder skills before you move to powered flight if that's what you want to do.
