I owned an Intuos 3 for 9 years until it died in 2013 and I am currently using an Intuos 4 that I've had since then. The only size I've ever owned is medium. I tried a small once and I couldn't stand it--the tiniest wobble in my hand caused ugly, jerky lines--it but I've never tried large. My intuos 4 only has around 2,000 pressure sensitivity levels and I'm thinking of upgrading it because the new ones have four times as much pressure sensitivity--meaning I can have WAY more variation in my lines much like when I draw with an actual pencil. That's why I'm upgrading. But I'm stuck at the decision of size. I can't decide if I want to get another medium or if I should go large. I have the desk space; that's not the issue, but I'm not sure if I would like the large. The reason I'm considering it is because it seems like I could draw big, gestural strokes from my shoulder. My logic is, if the medium tablet was more forgiving of my hand wobbling then maybe the large would be even more so? Drawing with an actual pencil I can draw quite smooth lines but on my current Intuos (the medium intuos 4) I'm noticeably more wobbly. Maybe on a large tablet my lines would look as nice as they do on paper? So what do you guys think? Go for the large? Or stick with medium?
