If Heinlein Grid wasn't working for you, that's because it's stronger together with False Lead. Then you can make them lose all their credits and two actions whenever you feel like it. C-c-c-c-combo!
Once you've accepted Heinlein Grid into your life, consider playing Director Haas instead of Private Contracts. Both are 3 to rez, 5 to trash, and are barely better economically than clicking for three credits a turn. But Director Haas is badass and can also fast advance things.
When they come to kill her, that's when you rez Ichi, Heinlein, and forfeit False Lead. Now they have no money, no programs, and a tag and a brain damage. That's why you don't mess with the Director.
Speaking of Ichi - if +1 strength on your Bioroids is good, why not double down with Experiential Data? It's not even unique so you can stack all three copies on a server and push your Ichi 1.0 to 8 STR - out of Knight and Switchblade range. Or just leave it unrezzed and people will think it's Ash and won't even bother running.
