Crystal Flash is a nice flash that looks good on most flies. Especially for coastal flies, this flash type is absolutely unbeatable. Easy to work with and with some great effects in the water. It lights up well and gives the flies that little extra that can make the difference on those difficult days. It is perfect for salmon, sea trout, coastal and trout fishing in general. Midge Crystal Flash is thinner than the regular accent/crystal flash, and comes in a range of really beautiful colors.
