I have a few questions pertaining to the build and upgrade path.
I was planning on maxing turrets and code gates.
Is this a worth-while investment?
I have read that Black ICE may be more valuable as a choke-point so have left it on level 1. Thoughts on this?
Should I de-upgrade my lvl 4 sentry to lvl 1? Reading conflicting accounts on this matter. I understand a lvl 1 sentry with a high lvl sentry is the "optimal" min-max strat?
I feel like having a second high level sentry could help push AV out faster and potentially cause a player to spend more time and/or shields to take down the first half of my base.
Those are the issues I have been considering thus far. Any other points or ideas gratefully accepted

Thanks.
