I have a 26 strings as my only harp, however I’m still a beginner and on a budget (and I didn’t want a low quality budget harp) and I plan to buy a bigger one when I’ll graduate from school and get a job (and a bigger flat!). I have just played on rented 22 strings so far so it’s still a few more strings than I’m used to 🙂
I really don’t have any advice to give, but good luck!
