I’m using an iCarez Matte screen for my previous iPad, and a Xiron Paperfeel Screen Protector for my Gen 5 iPad. The iCarez is much less aggressive but not quite as “paper like.” The Xiron does have a rough texture which I imagine will wear the pencil tips, but it is a better surface to draw or write on.
I figure if you are an artist or someone who uses an iPad to write on a lot, you kind of have to treat the pen tips like consumables, just like real ink and paper. That being said, I ordered 4 pen tips off Amazon and plan to change them out as needed.
