Not a big fan of tool-punched cartos, preferring the laser-drilled carto's more. Tool-punched cartos invariably distort the shape of the casing of the carto, which when put through the tank's endcaps can put stress upon the inner o-rings. These o-rings are what keeps your tank from leaking and also play a part in the tank's inner pressure, which can lead to flooding issues. Laser-drilled cartos do not have this issue.
To further protect your tank's o-rings, I also highly recommend a tank tool like this one:
A PBusardo Review - Slap Yo Mama Multi-Purpose Adapter - Big Daddy Vapor - YouTube
I also recommend Ikenvape cartos if you can get them. They're very popular and are in limited production, so are often out of stock of the ones needed for tanks.
I'll agree that there is a difference in the filler densities between Smoktek and Boge cartos. If you are having flooding issues, which are most often user error in origin, give Boges a try.

I have at least a dozen cartotanks set up at any given time, each with their own flavor. These are from different manufacturers, including IBTanked, the DCT polypro tanks from My Vapor Store, Elegance tanks from Hoosier Vapes, Vaporfexion, Valley View Vapes, and Phiniac. I've not had any issues with any of them.
I use Ikenvape 510 Fusion or Platinum cartomizers that are pre-punched.
