Recently I restarted using my Vision Elite rollerball and Signo gel pen, because the last notebook's paper didn't play well with my fountain pens.
While I love these pens as well, they require a little bit more pressure than a fountain pen, and their difference becomes very apparent in long writing sessions.
Being said that, they're probably the best rollerballs and gel pens you can use, because of their pigmented inks and archival qualities. Plus their blue black is a nice color, and Vision Elite can actually shade while writing.
