if you like them this much, stick with them until they die. then, when the liner or the soles wear out, contemplate buying new ones.
at that point, you are essentially paying 200 bucks extra for the ace of spades. all the AOS have that the Dub 6s don't is:
-rubber soles
-pants clip
-flex of "110-130" (versus the double 6's 90-110 flex rating)
I'm pretty sure those are the only differences. So if this is all worth 200 bucks for you, go for it! if not, stick with the double 6 and save a little $.
