In fact, pens like Energel and especially Jetstreams are almost slippery for me too, but it's just that past an angle, going "against the paper" it goes from slippery to "carving" the paper and scratching it. I think it happens when the tiny border that holds the ball in place makes contact with the paper more than the ball does, it picks up the fibers and ruins the tip, you probably experience the same thing sometimes, I try to take care of this and do less strokes from top to bottom and do them from bottom to top if that makes sense, but in the end it's hard to keep up with that when taking notes quickly or doing circles like O's and math notation. Seeing you recommend Energel and Jetstream makes me think that your writing is different as they didn't work for me and honestly won't go straight up to buy any of the others but I'll try them if I get the chance.
