There are few good fishing tackle reviews available, most fishing magazines are to scared to criticizes a product because they do not want to upset advertisers. Many reviews are just rewrites of press releases....
There are user reviews, but the quality of them can be all over the place and you really need to know the real experience (not just claimed) to know what importance to give their opinion. Rod companies also have a bad habit of using different names in different regions for rods which make it even harder to compare products.
The only quality fishing tackle review site I have found is www.tackletour.com , and I believe they are fairly genuine and unbiased. Unfortunately for us they are 95% Bass fishing.
