I would do more research on the corsair SP120 fans before purchasing if I were you. Those fans while having very good static pressure but it has it's own trade off (ie noise level due to high RPM). If you are one of those who hate noise, think twice before you buy those Sp120. Cougar fans you mentioned has very good airflow, good static pressure (although not as good as th SP120 one) but has much lower noise level.
If you run push/pull set up, the noise problem will be even worse. Besides, if you run push/pull, there is no need to sacrifice noise to achieve absolute high static pressure for each individual fan because in contrast to push or pull, in a push/pull set up, even an average static pressure fan is ok because you got 2 of those to do the work instead of 1 and the combine static pressures of 2 fans in push + pull will certainly be more than enough, especially in the thin radiator such as Corsair H100.
Having said that, if you opt to go push/pull set up, I would rather choose a quiet fan such as Cougar Vortex or Scythe Gentle Typhoon to achieve the same effects as the very high static pressure fans with loud noise. Note that with thin radiator like Corsair H100, the cooling performance is saturated once you reach a certain level of air flow/static pressure, so no matter how much more air flow/static pressure you increase once you reach that saturation point, the cooling performance will NOT go up much further.
