Penn Combo

Went to Walmart the other day, they had a bunch of combos in one of their famous box bins....figured it wouldn't hurt to snoop around in the box, found a penn combo, a 320gt2 reel and a penn slammer 7' heavy action rod....all for $59.95....someone put the wrong stick on the combo...haha. Talk about a deal right. Anyway, I'm going home to Orlando this weekend and was gonna go to basspro shops....I'm planning to put spiderwire saltwater fusion on the reel....and suggestions to the lb test?
