i've always done pulldowns w/ various grips...underhand, wide, plams in, and so on. until lately i started taking a real long bar and strecthing out farther than i have in the past and have started seeing an improvement (unfortunately i cant do as much weight but go more on form). if i want those wings should i concentrate on a wider grip and throw in the other grips every once in a while? and yes i do rows and all that good stuff too.
