I prefer them on big knives to give me a more neutral balance when doing finer things. I hardly ever use them on my 711 because I generally have a smaller knife for that kind of thing though. Personally, I think a dual grip handle with no choil would be the best of both worlds. Something akin to Blind Horse's machete where you hold it at the base to chop and up near the guard when cutting cord and such. Imagine the 711 with the res-c extending up the blade to give you an actual comfy grip on the center of gravity/choil area. I think about that every time I use a choil.

On small knives I absolutely hate them.
