OTB I would play 7/3 6/4, as I am a slow thinker.
Let us see how many rolls would leave a blot afte that. If I counted them correctly it is 65 65 54.
The alternative would be 7/1. Again this would leave 65 64 54.
I do not see what else is there. 5/3 5/1, but we would leave a ugly hole on the five point that will bite us later.
7/3 7/5 is very safe for future rolls but we leave one direct shot now.
At this point I fired up GNUbg, so I will not answer this one!
Same thoughts here. 7/5/ 7/3 looks very attractive on the long run, but I wouldn't have the guts to play it, so 7/3 6/4. And now I fire up something different 
1. Rollout¹ 7/5 7/3 eq:+0.841

And so leaving a shot now it was.
I would not have the guts to play this!
Same. I would consider 7/5 7/3 after seeing that 7/3 6/4 is a bit awkward, but without the quiz factor I end up playing 7/3 6/4 OTB.
