They are both way to big for all 3 species. The 650 weighs 22 ounces and has a line capacity of 250 yards of 17 pound mono...They are better suited for old drum and cobia fishing
Can't speak for other manufactures but as far as Shimano is concerned a 2500 and 3000 are the same reel with the only exception being the spool.I use a 3000 series reel and even it feels a little large for flounder. Considering downsizing to a 2500. Agree with everyone else, 650 is overkill
