the hardest stretch for me was the 4g to a 2g...for some reason, my ears bled so much on the first try (I waited about 2 and a half months)...I had to just downsize back to the 4g and I tried again in another month...hurt a little, but no problems
I've heard that from 2g to a 0g is the hardest for most people but I also did that on my first try XD (however I had my 2g in for 5 months) no blowouts, not even a drip of blood
I guess it depends what kind of ears you have
Right ear: 0g, two 6gs on lobe; 2g on cartilage....
goal: 00 on lobe! perhaps a 0g on cartilage?
Left ear: 8g, two 14gs on lobe; 14g on cartilage
goal: 00 on lobe!
