bobomacintosh, I agree with what the others have said. Will you be getting the kilt in the MacIntosh tartan? If so, you will be restricted in your choice depending on which tartan you choose. I think that Lochcarron has four MacIntosh tartans in 13 and 16 oz., but House of Edgar's Ancient Hunting MacIntosh only comes in 13 oz. (at least when I got mine). I would rather have had my kilt in 16 oz., but I preferred the House of Edgar tartan. I've worn both weights, and decided first choice tartan, second choice weight. Good luck; you can't go wrong with either 13 or 16 oz.
