Recommendation on CMEG best route option

Just curious if I should try another route for better ECN rebates. I'm currently on their commission structure of .005 per share. I've been using SMARCA route for pre market and market hour trading. Is there another route I should look into? I used to trade on NSDQ route but then there was a time that I could no longer use it pre-mkt and had to go to SMART route. From then I switched to SMARCA but haven't played around with others since.

Wondering what others are using. Thanks!

Edit: I'm also using Sterling Pro incase that matters.

Edit-2: Added pic for the routes I'm offered.
