Going back and forth on should I upgrade at WR or QB or just ride it out

Ok I’m been going back and forth on weather I should upgrade my WRs (Cooper, Godwin, Tyrell Williams, and Fitz) or QBs ( K. Allen, Cousins, Bridgwater, Brisset) by dealing one of my RBs ( Cook, Conner, Ingram, Fournette). Its a full ppr with a flex and super flex league (2qbs). I like having 4 solid backs just in case one goes down but part of me feels I should make a move, and if so who would u target. I’m currently 1 - 2
