Gary, I do have a supply of base and some pro boards left. I was going to go into more elaborate details but bottom line is since I made that poorly thought out reply above I rethought the idea. I don't want to cause harm to anyone nor do I wish to cause harm to any present seller of IBU products. I got out of selling because I'm just not suited for this sort of thing. As soon as you said 'bench tested' that was my red flag. Of course I understand why you would want that just as I would; I just don't care to rehash the grief I had when selling these for real so I'm going to have to bow out. Sorry.
Jerry
