WAS, I've been into khuks only a couple of months, and during that time I've been a customer of both GH and HI. Based on my own experience, I truly believe that in that amount of time the quality of GH khuks has improved significantly. The first khuks I bought from Craig were OK (certainly worth their selling price) but those I've most recently gotten are outstanding. I almost think that it is unfair to use the old tests to judge GH khuks because the overall quality has improved so much since the tests were done. It would be most interesting to see a new battery of tests done using current offerings from both sellers.
