I did buy the PCC carry case and it works out great for me. I carry 2 complete erolls and 4 or 5 tanks depending on if I have an extra atomizer in a mini Altoids tin. If I'm going to be with a group of friends (almost all of them still smoke) I get pretty bad cravings so I keep 1 eroll filled with 40/60 PG/VG and 1 or 2 tanks for the cravings. The others are 100% VG. The 40/60 gives me enough of a throat hit to still feel like I'm smoking.
