25 and 45 on two bodies w flash on each enough for wedding reception

I went to a friend's wedding reception a couple of weeks back. I took my E-M5, full grip, 25mm, 14mm and FL-600R. 99% of the shots were 25mm + Fl-600R. I used the 14mm for a large group shot but that was it. I'm still learning to use flash but most of the shots came out pretty well. I also had a GF1 with 7.5mm but the lack of flash meant ISO 1600 and most of the shots were pretty unusable. I think the 12-35mm would have been the best option if I had the £££.
