Hey Stiles,
On that particular carto, no you wouldn't need a drip tip. That comes with its own. I haven't tried those out yet. It looks like you got version 1 there though which has the shorter wicks. People have reported that those aren't so good in the sense you have to keep tipping them over to get them to wick properly. The 2nd version has longer wicks and allegedly alleviates that problem.
