are we talking about a G5RV or a Windom or both?  


I've had some success with both on the low bands especially (160 80 40M).

Off-center fed antennas are a really bad idea, primarily because they 
make the feedline a part of the antenna. This puts RF in the shack, 
increases the likelihood of RFI to your neighbors, and picks up noise to 
interfere with the stations you're trying to work.  A common mode choke 
could solve this problem, BUT:  the off-center feed places a very high 
common mode voltage across the choke, making it likely to fry.
