Well I brought a spool of 4lb fireline Crystal last night. Just took it for a spin up to the lake and I must say I am very impressed with the way it handles on a Spin reel. Also Found it good for knotting with the 6lb fluorocarbon leader snapping before the knot.
However the translucently clams are absolute rubbish the stuff looks like dental floss under sunshine and is clearly visible underwater It is however a bit less visible than standard braid though.
Overall i am impressed but a bit disappointed with how visible it is underwater.
