I use 30 lb. Amnesia on two spey reels. It doesn't unkink after hand-stretching as well as advertised, but I get by. It works well with a medium weight head. However, when pared with a 750 grain skagit head, it feels like walking a large, energetic dog with a thin string for a leash. For heavier heads, I prefer substantial coated running line, even if it doesn't shoot quite as well.
