Two JF-17 vs One Su-30MKI

Since Pakistan is unlikely to get a heavy fighter of its own it has to rely on a larger number of lights.
however is two JF-17s to one Flanker even enough?

(ok we know with PAF thinking of cutting down JF-17s down to 150 and continued IAF procurement of Flankers..its more like 1 JF-17 to 2 Su-30MKIs) 😮
