I've been using the big grid+ offering from Vela Sciences for my daily work. Only use pencil though, Graph Gear 1000. Recently switched from 0.5mm to 0.9mm. Have only been keeping "good" notes for a few years now and so far pencil hasn't been a problem. Was just rereading Jan 2017 this morning and even in 0.5mm, looks as good as new. I'm not in a real lab setting though so I just go with what feels good. If I was forced to use ink, I probably wouldn't take as many notes.
