Correct although here in Greece we sometimes play it with the rule: "The winner of the starting roll doesn't use the rolls occured to determine the starting player, but rolls again!"
So we have doubles as well. And actually i prefer that games although some of my opponents don't like this and play without doubles....

Hrqls:
D-6: Yep clear.....
D-5: Clear again....
D-4: Your prefered play is the one i play too in most cases....
D-3: Many things here. It depends on the mood:-) In most cases: 6-3(2) 24-21(2) or 6-3(2) 13-10(2). I used to play 13-8(2) long ago but i found it to be inferior....
D-2: 2 choices for me: I play regularly 6-4(2) 24-22 13-11 but when i don't feel confident(55 is devastating but if you escape you are OK!) go to the superior 6-4(2) 13-11(2)....
D-1: This is clear.....
