Why would you be reluctant to mention this? If there is a issue with your frame I want to hear about it. That was pretty much the deal from the beginning.... I supply a cheap test frame, you shoot the heck out of it and provide an opinion. I appreciate you guys going through this T&E with me but you have to realize you are not doing anybody any favors by not mentioning a failure if you have one.
If the frame is not performing in an acceptable manner all of you have the option of returning it. I will give you the credit you originally paid on the next frame which will be available this month.
