The seagate is a great reel but is more for jigging as opposed to popping because it has a slower retrieve, I use mine as a medium outfit with 50lb braid and matched with a Daiwa Monster Mesh PE4 its a great little rod with a softer tip for a better action and good back bone best of all its cheaper( King Fisher are clearing them) and lighter than the poseidon .
For Popping in that price range go with the Poseidon 8 ft it has a better action than the 7 ft version and go with the Saltist 6500H or the Shimano saragosa as these 2 have a faster gear ratio which is better for popping.
Happy shopping and tight lines
