So being unsure, and wanting to make sure and get this right when I order, is the Boge 510D XXL the same as the boge XL? The reason I am asking is because I am ordering the following tank http://www.yourcig.com/product/agr-atomizer.html it has Two size clear tank for Boge carto 510D and 510DXXL and I want to get in on the boge co-op right now but don't want to order parts I can't use. The two listed in the co-op are boge normal and XL. Thanks in advance!
