I'm also looking at the MEFI4 unit from MSD (formerly from UMI Racing), which is smaller, can be mounted in the engine compartment, and supports knock sensors - but is bank-to-bank only. I've only ever used SEFI controllers myself.
Is there truly a significant difference in idle quality with SEFI over bank/bank, in people's personal experience? I plan to use a fairly big cam, and the Pro Stock type of idle gets old pretty fast.
Thanks in advance ...
Edit: I do know that there is a difference with large injectors, due to the injectors firing half as often with SEFI and therefore minimizing injector opening time issues - but the stock injectors on an LS7 are not that large (42 lb/hr).

I've made over 1000 hp and run 95# injectors with bank to bank, no idle issues.
