My opinion is that STP has very little to do with the career that Knopfler has as a solo artist. For me, first MK solo record is Ragpickers, from that one, he found his path.
GH was experimentation looking for his solo character, STP was a mix betwen the old MK from the Straits days, and the MK he wanted to be as a solo artist, and in RPD he already found what he wanted to be.
I understand that people like STP the most as it's the most DS MK solo record, but that record is not the MK solo artists. People who thinks that's the best, is because they like more his Straits days than his solo career.
That's why I would keep voting against STP until the last poll, or until it gets out, what happens first.
