Not sure about a blank, there are some others who can help you with that.
But I can offer some advice, steer clear of the Captiva's reels. I bought 2 to "test out" a few years back when they came out. 1 baitrunner model, and 1 non-baitrunner. I blew tha handle off one fighting a 25# fish. White metal. Rubbish. I hucked it in tha trash. I still have the baitrunner model, but I use it for fish up to 15# when chunking bait in the marsh. The bearings are smooth, but the drag is really "chunky".
20# Fireline is great fer pluggin', especially topwater plugs. It's got "body", and isnt as limp as the ropey braids are. But I wouldnt recommend it for jigging or when working around alot of rocks and structure.
