Repiping options

Now that old man winter is loosening his griip, I hope to get some repiping done. The reason for repiping is a 2nd floor rad which doesn't heat unless one of other 3rads attached to same branch are turned-off.  The branch is a 1" pipe which is reduced to 3/4" after 2nd lateral off run-out, and runs about 20' to riser to radiator in question.  All rads are piped well and there are no other issues other than too much radiation attached to run-out.  Several solutions are possible: (1) repipe entire line with 11/2" pipe, and laterals with 1"; (2) repipe lateral with 2 rads attached to main; (3) disconnect last lateral and attach to existing 11/2" run-out which has one rad of 50 edr attached.  See attachments.  What is best choice?

    At the risk of sounding flip...

    whichever is going to result in the simplest installation with the correct pitches!
