That'll work as well, and will work in pre-0.10.10 releases.

None other than the ability to make "dissect traffic on port 6660 as 
HTTP" a permanent setting.  "Decode As" changes the table that maps 
ports to dissectors; the HTTP dissector option causes the HTTP dissector 
to register itself in that table with that port, so they both affect the 
table.
