My advice is just get some SS reels and practice. I hold the reel and the end of the film with my left hand to start/center it in the reel, holding the film roll in my right. i then move my left hand and fingers to gently curl the film as it starts to wind, drop the film from my right hand to let it hang free, and then use it to gently turn the reel while still guiding and curling it with the left. A bit of practice and you will never go back to plastic reels.
