First, you need a good quality limp line. Trilene XL is a good start. Steer clear of fluorocarbon or any of the new lines for now.
Second, don't fill the spool more than 1/8 inch from the spool lip.
Third, make sure the line is going on the reel the same direction it's on the spool. You don't unroll the line, you take it off the side of the spool, just like it comes off the reel when you cast.
