Up to this point my photography has been a hobby/fun and somewhat of a passion. I make a 'small' amount of money doing a few art festivals each year but no where near enough to support this addiction. I have done 3 weddings over the last two years (for free) and the bride and groom have been very happy with my photos.
I am seriously thinking of doing more weddings and art fests as well as some portrait work and other projects to make some money.
Here's the problem ... I have a bunch of money invested now and don't really want to invest more without being sure it'll pay me back. So far everything has been shot with my one 10D. Although I keep coming close to getting a 5D (and 10D as backup) I keep balking. Now I'm thinking of getting a 2nd 10D so 1) I have a familiar back up if needed and 2) I have different lenses using each so no more fumbling during a wedding shoot to change lenses.
THEN, if this pans out I'll be shooting with that 5D!
I know you can't compare the 10D with the 5D but the 10D is still an excellent camera and has done me fine so far.
Please show me the flaws in my plan. Thanks!

For weddings you may find the FF much more usable for wide angle group shots. If you really enjoy/love photography I suggest you get the 5D (if you can) it will be well worth it (it was for me).
