it all depends really.. How relevant are the LLL infront of the first word? If they are just letters perhaps not a good idea.
3 keyword domains are a bit long tailed but can still be worth it, if the keywords are right.
This is a perfect example of what I'm looking at. The three LLL infront of the word are the first letter of three dictionary words that describe the site.
In the wordAwordBwordC I actually remove a key dictionary word to shorten the domain. If that makes sense.
