Which line to use

I'm going to buy a Diawa sealinex40 for my heavy duty rig. I will use it for Islander trip type stuff, sturgeon etc. What line do you guys recommend? Should I use mono or braid? What weight?

That thing will swallow a lot of braid $$$ so you probably want to go Mono/Braid/Mono. I like to stay in the middle range of recommended weights that the reel is rated for,adj the topshot for my target species.

I just picked it up at Sportsman's wearhouse for $104 and I bought a 7' Ugly stick Tiger medium action rated for 20-50 lb line. Now I just need a penn 500 and I should be set. Sports chalet has Penn 500/Penn rod combos for $69 but the rods are very stiff.
