you have a couple of options on the ML series aside from selling them:
1. Replace the drag washer with one from a standard AL series. It is larger in diameter.
2. Form a cork drag washer the same diameter as the drag plate portion of the sleeve.
I've replaced the standard drag washers on the AL series reels with cork, per a recommendation from John Brazelton at Redington. Over time, a combination of grease/oil and debris on the standard drag plate reduces drag capability. That is why I went to cork.
