Gday mate, with a 3000 reel, 15 pound braid i reckon(if braid is what your after) would be the way to go, I have 15lb braid on my Penn applause in the 3000 size and had a ball fishing sp's for reddies up in forster over christmas. Just a personal preferance mate but you could get away with 20lb aswell- just stay clear of 30 pound unless your using a size 6000 threadline lol
