+1!! It’s a risky approach of course to present as edgy, and so it will be hit or miss. The alternative is to sit back and take your chances as a plain vanilla candidate facing <10-20% odds as an unhooked but very high ability/high achievement kid at a school like Harvard, most of whose applicants are adhering to one standard script or other. (Yes, I know the stats might suggest even lower odds, but remember most unhooked applicants are basically instant rejects.)
