80lb Power Pro would be my choice. Get the reel backed up with 50 or 80 lb dacron and then get about 200 yards of the power pro. Adding the backing will allow you to save some money on the expensive stuff. 200yrds is about all you wouuld ever need for line and it would cost somewhere in the range of 26 bucks. I would prefer the 80lb line because sometimes you may need to fish upwards of 2-3 lbs of lead.
Hope this helps!!
