If you are going with Eheims, I would recommend running two classic 2217s.
I have a 120P for many years and I have ran the following configurations 2028+2215, 2028+2217, 2075+2217, and finally I ran 2075+ES1200.
I found the classics series to be 'better' than the pro2 and pro3s because of the simplicity of design (no bypasses, no primers) and constant flow in between maintenance (the pro's loses flow much noticeably). If I were to do another one, I would stay with classic style canisters.
