B Main Defending 1-Way Smoke
As if this site wasn't hard to take already, this oneway is a great substitute for the usual cypher defense. However, you have to be playing on the site to use the oneway rather than throwing the utility and running away (like Cypher).
A Main Ramp 1-Way Smoke
Easier and more lenient oneway. It's not a true oneway but you will definitely have the jump on attackers.
Mid B Side/Market 1-Way Smoke
Strong early round 1-way for controlling mid and finding picks on peekers.
A Heaven to Ramp 1-Way Smoke
Difficult but extremely powerful 1-way smoke to control the entrance/ramp to A Heaven.
Defense A Main One Way Poison Cloud
This smoke gives one way vision of A Main from site
Defense B Site/B Main Screen
This wall blocks vision of B Main and gives a wide angle to see anyone pushing through
