wanting to upgrade

[big red chuker]

Any recommendations for upgrading? I have a awesome custom 18650 parallel box, infinite stingray and atomo. My friend has a paragon midnight v2 and flawless tug combo. Any of them a keeper? I'm wanting to get a harder hitting device and don't mind going authentic. Any advice would be greatly appreciated?

I'm a fan of variable wattage, made from stainless steel - until I find something made from titanium, with temperature control. I really want a titanium tank in the shape of Panzer or something.
