I've had success so far refilling Bloog MF Cartos with Backwoods Brew, Freedomsmoke USA and Dekang juices. I'd heard good things about Boba's Bounty from alien Visions, so I thought I'd give it a shot. I filled a previously used Carto with Bobas and let it sit for 10 minutes.
The results just weren't that great. Boba's is certainly an interesting juice flavor, but it's 100% VG, and as such it is very thick. I was able to get a bit of vapor out of the Carto, and I didn't have any burning issues, but there is nowhere near the vapor production I am getting with thinner juices that are a blend of PG and VG.
I was curious so I did an autopsy on the Carto, and there was no evidence of burning. The 100% VG is just too thick to work it's way from the outer polyfill into the second polyfill and finally the wick. The hits were very airy, as the juice just wasn't making it's way to the inside of the Carto.
I've included a pic, so you can see that everything looked good when I took it apart.
Note: All BwB juices are 70% PG and 30% VG, and they work great. I picked the same 70/30 blend in FSUSA flavors and have had no issues. The Dekang are, of course, 100% PG, so wicking is not an issue there.
I thought I'd share my experiences with everyone here. Perhaps someone else has had luck with 100% VG, but I have not.
