I have 8 50's and 8 100's - like 'em all - also for the direct drive feature. I had John's in Everett put a direct drive button on the 50's. Don't know if they still do that - sweet. Also reiterate about loosening the drag. Both reels are relatively easy to take apart and clean. watch out for the 2 little springs on the right-side. There is a large fabric washer, also on the right-side spindle that controls the drag. It will tend to wear and flatten out. Linc's in Seattle has spares - or Marie there is an expert in cleaning and repairing both types of Shimano's. Good luck.
