Even Jarrod doesn't list those as bouts. I'm not doubting the coti would be a great choice but it seems as of late no matter what is asked in the honing section of the forum the coti seems to be touted as end all be all. Even when the OP has not even asked about them in particular.
You're right, he doesn't. Jarrod's previous listing of "travel-specific" stones was listed as bouts, but these ones are as well based on Ardennes' sizing scheme. Anyway, I was simply replying to your question and ensuing statements. Although I do personally think that these little yellow stones are the best overall value (and fun to use), I have no interest in crusading. If someone chooses to use something else, I honestly don't care one way or another. My only interest is in providing factual information and my preferences when the occasion arises. I don't see why there's a problem with so many people sharing this opinion lately as that is what has been asked for--people's opinions.
