One of my buddies is using 1-AD right now and he says it is great. I have seen several people say similar things about 1-AD on AR too. I read that 1-AD converts to 1-Test. I see now that companies are selling 1-Test, so is there any reason to use 1-AD anymore? If 1-AD converts to 1-Test why not just cut out the 1-AD and just take 1-Test?
