If it only happens with top-water maybe there isnt enough resistence...
depending on where you fish here's what I do...
hope your backing is on tight...
go to an outflow (preferably uncrowded, mid-day is best)
cast as far as you can with a
darter/huge swimmer
freespool as fas as the current will allow.
grip line lightly with a glove, and reel it back on.
packs the reels very nicely.
My guess though you are throwing slack with it on the spooks/pencils
