I had spider wire which I was very very very dissappointed in. I restrung with Stren and have been very happy. That is some light...strong line. The spider wire is darn strong...untill you put a knot somewhere. It seems like the line is too brittle? Always breaks at the knot. I tie a standard palmer knot.....no stronger knot that I know of for tieing tackle. Ken swears by it.
8# is in my opinion a good all around line but its too heavy for me....I might put it on a poll that I only plan on trolling with, to help retreive hung jigs but I dont want to put it on a poll that I am working with. THe 6# seems to cast further and just seems like I can cast more accuratly with it. My own limitation I know but hey...we all like and dislike stuff for different reasons.
I am sure spider wire makes bad to the bone fishing line.....but thier 6lbs test sux ass. Stren has been around since I was a wee boy and they have always made good line
P.S. I will look for the 8' they would be just about perfect....the size and color are important too though. If I can find em in Chartruse I will get some. I didnt see any while I was there last time. Thanks for the heads up!
