EF-420 (4 element 30' boom) or a EF-420S (4 element 24'  boom).  To
grossly over-simplify, the 420S has about .7 db gain over  the C3 and
the 420 has a little less than 2 db gain over the  C3.

The bottom line for me always has been  "Can the JA's (or other DX stations) 
tell the difference?" when contemplating  any kind of antenna change. In this 
case I'd have to say no so it's a  pretty marginal decision.
