I found the OG essays to be a good start.
PR has a template and some key strategies for AWA.. the strategies are good but I'm planning to avoid the template (for obvious reasons!!)
I think if you read Kaplan or PR or OG for that matter... the structure proposed is common....
For issue
<Intro>
<Examp1 - supporting/against>
<Examp2 - supporting/against>
<Examp3 - supporting/against>
<Conclusion>
For arguments
Similar structure ... but you are now attacking various assumptions that either support or weaken the argument (most times you will be weakening the argument anyway) .. so the structure will be
<Intro questioning the argument>
<Examp1 against/for assumption>
<Examp2 against/for assumption>
<Examp3 against/for assumption>
<Conclusion weakening/strengthing argument or what missing assumptions would further strengthen/weaken it>
I think all books mention.. never take an extreme position.. or I translate that to.. be as politically correct as possible
