Before rush began, in both the spring and fall, we would sit down as a group and list things that the house was lacking or needed to improve. Grades, community leadership, people with a performing talent (singing, dancing, etc), etc. - the needs of the house. During recruitment we would look for girls would could help bring something to one or all of these qualities that we were looking for. We never targeted one specific group, aside from a group of friends (we got 2 to join, and 4 of their friends ended up joining!), we just looked for what we needed.
But by targeting only one specific group or looking for one specific thing, you're going to find that you end up lacking in other areas. Diversity of interests, talents, etc. is the most important!
