I decided to look this suited aces thing up via google. Ive only come across one article so far that talks about A2-A5s vs. A6s-A9s

Now to answer the question of ATs and above and A5s and below versus A9s A8s A7s A6s, I like the first ones because you can also make a straight with them. I would take A5s over A8s because the A and the 5 can work together to make a straight, unlike the A8s. When you play weak Aces though like A5s, you have to be extra cautious if you catch an Ace on the flop. You won't be sure if your kicker is good or not so you'll have to use some more thinking. Playing these only in later positions can help you make better decisions because people will check most likely if they don't have the A or that hand beat.

BTW, I use to post on RGP and I NEVER got as much food for thought as I do here at FTR!
