Different drip tips don't make a big difference on this, to be honest. It's under-the-coil airflow and there's just not a lot of it. Have you ever tried a Narda? That's about the airflow you can get full open.
I passed mine on, just for the airflow. Considered drilling some holes in the side, but that kinda negates what this was made for :)
It's a flavor atty though, really good vape, just not for me.
There's a thread on here with a bunch of people who already have theirs and most love it:

I'm a Hadaly fanboy. I like the Wasp, but I tone the airflow down quite a bit on it. Just to give you an idea on how I vape. The Wasp is too airy for me, and even for me this Nixon rdta was too tight.
