Finally upgraded to an a7iv for my cousin's wedding this weekend and man, the burst speed is wild. But my old cards are literally choking on the buffer and I cant keep shooting. Need something super fast and reliable that won't blow my $200 budget. What V90 cards are you guys running for fast action?

I have been super satisfied with how my cards handle that specific setting. If you want to stay under that 200 buck limit, you actually have some killer options that perform just as well as the expensive Sony stuff. Here is what I have been using with zero issues:
