Just curious if anyone uses the blank XL cartomizers. I'm using the regular 1 ml size, but it would be nice to try the larger ones that hold more juice!! Are the larger ones as good performance wise as the standard size SI blank cartos? I'm having no problems with the regular size & the 100% vg I'm using --- filling just takes PATIENCE!! So can u guys give me your opinions if you use the XL ones? Thanks!!!
