Hey Red, thanks for the answer...yup, it was late and I suffered a severe brain fart. You don't use atties with cartos...duh!! Don't know what I was thinking. Think I'll give them a try...the O-ring on my drip tip should be able to compensate for the sloppy fit...If not I can just slip on a fatter O-ring.
Thanks Red!
I use driptips on them with no issues of fitment. I have some from 3 different vendors and all fit fine.
