I use 100% PG. I like it because it has way, way stronger throat hit and crisper flavor. My experience has been that VG mutes the flavor a lot, I'm not a huge fan of it.
I haven't had any issues with a lack of vapor production. PG does produce less vapor than VG, but it's not like there's NO vapor. Also, I've used PG in all manner of systems including tanks without experiencing leaking of any kind.
BTW, way more people are allergic to PG than VG. If you've been using 50/50 mix, how do you know it's the VG that you are reacting to and not the PG?

타격감도 좋고 향도 많이 살아난다고 하는군요
100pg가 가능은 한것 같은데 이 게시물이 2011년도 게시물이라 확실하게 검증된 방법인지는 모르겠습니다.
pg알러지가 있는지 확인해보시고 사용하시는게 좋을것 같네요
