Hello! My Huion 420 (not H420) tablet just arrived today, and I'm still having trouble determining what scope dimensions I should use. I know I'm definitely not used to it yet, so that is most likely why I'm sucking (a lot), but what are some of your guys' dimensions that you personally use? This would help me start off and try out new dimensions to see which fits me the best, rather than randomly inputting numbers and seeing how well I do. Thanks in advance!
