The best Astral constructs

[Irk]

All i need are the best menu option from all the sources (minds eye, potpouri, whatever).
I know it is situational, so is it worth printing out?

Edit: I'm making 5th level constructs and thinking improved fly, power storing and extra arms

I like having one specced out to grapple. Things like Brawn and the one that gives Imp Grab. Constructs can get big, and even at high levels, dropping a huge grapple monster on an enemy can make them uncomfortable for a round or so at best, and could end the fight at worst.
