Let us know what twins set up you go with and how it turns out... I have been on the fence for sometime now about twins vs a nice single... so I'm interested to hear the results
Unless your running the "texas mile" or towing you could probably hit 1600 daily on a 12v without issues. Or add water injection. Or go slower. My 12v daily driver peaks at about 1550 with a 64 turbo and 5x.014.
