My opinion is go with Seguar Ivnisx. You will not be disappointed. It's very strong yet manageable. Put it this way, I don't use my spinning rods very often and don't respool them very often but when I pick them up to use them I have very little line memory. If you buy bulk 1000 and 3000 yard spools you'll save a little money.

However, If you have extra money to spare go with Sunline Shooter Fluro. That is awesome stuff but very pricey.
