I would do the AW. It's a fantastic race - you can treat it as a recce towards a future TWA attempt
I think you may enjoy AW so much that you would want to do it again though. For me it has the perfect balance of breathtaking scenery, climbing, runnable terrain, and when the dates fall like this it presents me with a very good last run out before the PPP.
Knowing I have the PPP the week after allows me to run rather than race and enjoy it to a full as a consequence.
