I find it very useful, problem is I can?t find it - at any local fly shops , - I still have some but,- thinking alternatives ,- rubber bands ? colored ones may be just the ticket..----As far as loss ratios really don?t matter to me, -but that is suppose to be the main reason for using it.As for me I just like the nuance of a gentler cast and to each his own ,- but you may want to try it - or not -easy to incorporate into your setup ,- just an Idea to cast out to anyone interested. Be safe
