Good hard capped cartomizers?

[ThunderOne]

I started on the Mistics and just recently got a kit from Volt. I still prefer the hard caps vs. the soft ones and was wondering which cartos that have hard caps were the best. I see some from Boge and LiteCig and was wondering if there were any other options out there or maybe I'm just overanalyzing and they're all built the same.

Thanks in advance

I like the boge. They perform well as long as you keep them wet. The 2.0 ohm work well at 3.7v. I havent seen the hard capped ones. where did you see those?
