It's very possible, my brain implant adds 65 psy, and I don't use fly catchers, burden, computing rings, VTEs or genius perks.
I used to have the 180 brain in and still have 781 psy but I felt it was a bigger sacrifice to keep +psy items in other locations where I could've had something better since I don't need the nanoskills from the brain.
Now with research we have another 35 psychic, which means I'd still have to put on more psy items if I put a brain symb on. I will consider the loss of the items vs the saved IP when I do the IPR, but I think i'm sticking with the implant.
