Just want to put in my two-cents for future readers. Anybody can be open to criticise me or whatever but....
By 10-11 minutes you can easily have tech out such as collo or HT. In this situation where they are pushing you, they can easily tech switch into either counter, but collo would be more stable. If you could easily engage in a choke with some decent forcefields go HT because they are a lot handier in defense than collo.
Reasoning behind having HT on the defense is because you warp in 1-2 at each base with some zealots and any drop that comes in you storm and feedback and it is shut down. FEEDBACKS are underrated!
Chargelot archon with some sentries isn't a bad choice. WHen chucking up the third convert into Collo production.
