[Elecraft] G5RV medium power Balun

I recently purchased a "5K watt" PVC balun from a very well known supplier of wire antenna and baluns.  This supplier has a G5RV antenna that they are marketing with this balun.  

I believed the vendor that it would work on my G5RV; particularly because I am running medium (not high power) of 600 watts from an AL 811-H.  The balun saturated in 1 hour of operation and failed.  The "expert ham and marketer" at the vendor did not call me or e-mail me when I asked what the balun power specification is at the G5RV ladder line SWRs which vary from 1.9 to 8.2.  I operated in the 1.9 to 6.0 range.

I also emailed 2 other well know more expensive balun vendors asking them what the specifications were for their baluns at the above SWRs.  Not one of them would e-mail be back in spite or their recommending that I buy their balun.

It appears that none of these baluns would work and that the only solution is to use a coax choke (one balun vendor did tell me this).  G5RV indicated this in his write up of the G5RV many years ago.  Is this correct?  What are your experiences?
