When I first got the RS2e before much burn in...the Flats worked well...but after longer burn in, the RS2e upper mids became more emphasized and hence the Flats just became more shouty. But that is to my ears. Don't let that stop you from getting the Flats but just to give you some reference. I've heard the GH1 might work better (than RS2e) with Flats. But I'll find out soon.
