Glad your experience went well.
As a suggestion, get two F1-812 and two F1 subs. For ceremonies, one F1-812 will be all you'll ever need using the various inputs for a mic, a handheld device, a mixer, etc. For really small events, a pair of F1-812 on a tripod in the reverse C configuration are awesome. For larger head counts, use a pair of each. Yes, in most cases a single F1-812 and F1 Sub would suffice, but it'll be mono which is like listening to AM radio. By using a pair, you can run stereo and bring the music to life-like depth AND have a running backup should (heaven forbid) one side craps out.
There has always been controversy stereo versus mono versus perceptible depth of discernment. A line array produces a 4 times greater depth of stereo field. That's a significant increase over conical. Also, running in stereo with speakers roughly 8 - 10 apart greatly reduces potential cancellation. Running in mono, the speakers should be 18 to 20 feet apart which is really absurd but necessary.
