Luke has made pretty clear why he has made his choices, largely connected with enjoyment and motivation ( oh and no doubt he may potentially earn quite a lot more ) and that seemed very much just about himself irrespective of anything to do with say the LTA. I find it very difficult to see how anyone else can say his path is wrong for him.

OK, Jaggy does, but that seems rather more about his thoughts on doubles than on what is best for Luke, particularly what Luke feels is best for Luke.

Jonny, I don't know his thoughts. One thing, of any relevance I don't know, is that he appeared to have a lot of injuries as a predominantly singles player and not so as an essentially exclusively doubles player. Ultimately he also, as flamingowings says, must be doing what he himself wants to do.
