T-type cover letter is best used when the job opening give detailed requirements and qualifications, such as college degree, number of years experience on specific tools and languages, professional certifications. If your background matches most of the requirements or even exceeds desired quantities, then T-type is perfect.
Don't use T-type cover letter if there is no detailed requirement list, or your qualification doesn't match well, or you are over qualified.
