Just like to say thank you to everybody who has given me advice and tips since I joined the site and can now say I have a understanding on many of the different (and confusing) aspects of vaping. I've found my level. 2.5mil of American red. 1 mil of spearmint. In a 3.5 mil vivi nova with a 1.8ohm coil topped with a 1100mah ego bat. Perfect happy vaping . Regards lee.......
