See the Choke Cookbook and text that  precedes it.

An off-center fed antenna is inherently poorly balanced,  so it puts a 
high common mode current on the feedline, which in turn  places a high 
common mode voltage across any choke. It is well known that  even very 
good common mode chokes are likely to fry (fail destructively)  when used 
with even moderate power levels. You MIGHT get away with it at  100W, but 
at some higher power level it WILL break.

So, is there ANY solution to providing a feedline choke for an OCF dipole  
used with high power?
