Sorry..I agree with using heavier line for heavy weed..but 30-50 pound..really? You'd tear a bass' mouth apart before you had to put that kind of pressure on a fish.
I've fished 20+ pound carp out of lakes like Ripple on the Blackstone that are nothing but weed with 15-20 pound line.
I've also landed up to 8 pound bass on a 8 weight fly rod that goes to a tippet of 12 pound through very weedy conditions and have never had line test become an issue. The only fish I lose are due to bad hook sets not broken line.
That said I don't really have a braid preference, even if I did most of em are not found here as I buy em mainly for carp fishing hook lenght.
For mono/co-polymer I like Mcoy. Mean Green is exactly that... Mean and green. Also Braid sucks in my opinion for fishing areas with sharper snags like rock ledges and heavy timber. It just doesn't hold up well to the abrasion that a good mono will.
Also wanted to comment about some of these gimmicks the fishing industry use. Seen that someone mention the Cajun Red line, which I do like, regardless...I find it neat that it says that red is the first color to disappear underwater which makes the line invisible but yet we should buy red hooks because the fish thinks our bait is bleeding. Fun right?
