I would highly advise two things: 1) Head to your local guitar shop and handle some guitars. Talk with the employees about your goal. See if there aren't different neck shapes/widths that help you achieve this. 2) Made a 1on1 live lesson with one of our instructors. This way, someone can see how you are approaching the techniaue and evaluate what you can do to better help yourself! Maybe there's an approach that you haven't thought of, but an instructor would be able to point out to you. Good luck!
