A piece of negative advice - steer well clear of Shakespeare fly reels - at least the Alpha and the Omni X. The drag went on 2 of the Alphas and the gearing on the OmniX, all soon after buying them. False economy in my opinion.
John Norris have reduced the price on their own brand "Professional"lines from £19 to £13. I find their lines more than adequate but haven't enough experience to compare them with more expensive ones.
A lot of people on this forum endorse the Pitsford Pirates lines for value and quality. He will also give you good advice on which line etc.
Hope you get some more answers soon
