B – the most grippy of the four, but only slightly more so than HB/standard. This, and the standard pen (if they’re not same thing) both feel great for standard note-taking and precision stroke drawing. This feels very similar the standard pen nib, which has a strong, if even slightly rubbery, surface resistance. I haven’t confirmed that for sure though. HB – I’m can’t exactly recall, but this might be the same as the standard nib that comes with the pen. It’s extremely faint, but I detect just a bit more resistance when drawing with this nib. It feels much more conducive to precision drawing. H – similar to 2H in slipperiness, but with a much thinner, even a bit harder tip. I’d love to use this for super fast sketching, or for drawing extremely long, flowing curves. It also feels like the softest of the four. The slipperiest drawing experience I’ve ever had on a digital display, and that says a lot, as most of them are pretty slippery. 2H – the thickest nib of the four, and it’s SUPER slick. The store staff also allowed him to test the new pen nibs and his findings are fascinating and somewhat disappointing.
