Are those 16g cartridges? I can't tell from the link, so I'm worried that they are 8g.
I think they are 8g. I have a TAD as well so I'll just plan accordingly. I would search on Ebay for some 16g. There were a couple sellers with 16g CO2 pretty cheap compared to the local stuff around here. Though the earlier link of williamson supply was the cheapest non-ebay I saw on a quick search yesterday. Good luck.
