I'm not against him getting a break, but if he does take time off he should at least pause payments as well.
aside from that, none of these options are all that appealing, they seem to essentially be the same idea with small variations, at least at a glance. The only some what interesting ones looks like #17 and #3, though I doubt either will win.
