Never used it in fresh water, but I am using a 15lb leader in the salt on the Gulf of Mexico, both surf and bayside.
Not sure if I am getting more or less hits, but it is stiffer than mono and has less abrasion than braid.
Some people swear by it, I don't think it is magic, but don't have anything bad to say about it and does allow a thicker leader for rough cover, so at least it is a plus.
