I would strongly recommend a Personal Quick Link Invitation for LinkedIn Lawyers.
As Lonny Guilden explains on the Quick Link signup website, many members find Quick Link useful only after our standard allotment of LinkedIn invitations (typically 3000) has run out.
However, I would advise that new LinkedIn users get a Quick Link right away. LinkedIn invitations are a valuable and quickly expended commodity, and as such they should be saved and protected. A Quick Link can be used much like an invitation, but is sent via email.
One of the hurdles networking lawyers need to overcome is the LinkedIn skills of their fellow lawyers. Using LinkedIn invitations only when absolutely necessary saves invitations for when a ease of online media use is critical for connecting. Many lawyers are not familiar with LinkedIn, and using a LinkedIn invitation may enable that lawyer to connect.
