Best Cart Mod?

[Skyrish]

I recently watched a video of a pyramid tea bag mod for cartridges, was wondering if this is the best mod or if there are better ones

In my opinion, don't waste your time trying to mod your carts. If you want to stick with a slim battery device, I would suggest 3 Ω cartomizers. You can make them last quite a while before you need to toss them by keeping them wet and not vaping them totally dry, scorching the polyfill. They are relatively inexpensive, too.

Back when I was using cartridges, before I started dripping, I found the blue foam to be better than Pyramid Tea Bags.

Also this mod seems to be very easy, and very popular with those who've tried it...
