Well... yes and no. There's not enough econ, especially not against whizzard. DBS usually counts as econ, but is bad vs medium, but I'd still keep 2 copies. Using CVS to counter medium was a desperation play and definitely not recommended as plan A. I think the best way to beat medium is to just make enough money to rez (and defend from parasite) a booth or ichi on R&D, and the best change for that is to cut the CVS, cut a wraparound, add the 3rd SFSS and 1 marked accounts. 1 fast track is probably best; 2 is a luxury the deck can't have right now.
As for lotus, double gear check is good but I hate it when my ice becomes blank in the late game. There's apparently a power shutdown + lotus NEH list going around that I haven't seen yet, which is probably way better at beating medium if you find your combo at the right time.
