hey, i used to surf when I was in middle school, and now I'm a sophomore in high school, and I want to start again. I went out last week, and I forgot everything. I have a 6'10'' Realm surfboard that I'm borrowing (which I have to return soon), and a recently purchaced a 5'9'' surf prescriptions shortboard. Do you think it's possible for me to re-learn everything on a 5'9'' shortboard? I am 5'7'', 100 pounds, and I skate a lot.
