Besides what the insert says for the Siam mods tip does anyone have any other tips? I lubed up with some straight VG on the inside of the drip tip and a bit on the outside of the io6 and pushed rather hard to no avail. In fact I ruined a 1.5 io6 after it got lodged in my PV (luckily just an ego as I did not want to risk it on my buzz pro) and the attie was not that old. But getting past those o-rings is uber tough. My Empire Drip shield does its job for my 510s and takes a bit of elbow grease but this thing is just ridiculous. To be honest while I adore the io6 with pryex tip, I will probably just return the Siam mod. I made sure I was pushing straight down as possible without just getting out a level
