Hi My guess is that the flash on the (non-Canon) extension lead will fire on full power, which I think is the default when only the centre contact is connected. You could reduce this by firing into or through a brolly. I'd suggest running a trial film and varying apertures, set-ups etc. and keeping good notes. If you're trying to set up a small studio which you can return to with the same lighting arrangements you should be OK; if you're trying for some more portable set-up you'd probably be better off relying on one flash, controlled by the E-TTL system and using reflectors to give you more apparent sources of light.
Saving up for a 2nd 550EX is definitely worthwhile!
