I'm really no sure about this so I thought different inputs would help: When seving in doubles, does the area in which the shuttle lands can be from the the service area, between the side tramlines and in the backline? I'm really confused about this cause i don't think you include the backline part but my friends say it is. But what I've researched is that service in doubles is wider but shorter than in singles. I'm not really sure about this however. (I've researched only one site) Thanks for the replies.
