Hello Imeo and friends.
Unfortunately I never owned a GG mod. I've only had the fantastic GG RBA's. This is why I'm excited about getting Proteus, because it will be my first GG mod.
I wanted to share my part about what I think are one of the biggest weakness of a mod. The weakest part of many mods I've owned is the insulated center pin. Users have a tendency to screw an atty/RBA too tight. Or over-tighten. Causing the pin to get pushed down...not making connection, and even breaking the insulator.
The best solution for this problem is up for debate. I've had a mod where the center pin was spring loaded, but after some time the spring broke and the pin was stuck in the mod...rendering the mod useless. Other mods have a screw on top cap...so you can always take the cap off and fix the pin if needed.
As I mentioned earlier, I don't own any GG mods so I don't know how the center pin is on them. But I just want a reliable mod. And the center pin problem is one of the most common problems.
This is why I like the new Penelope V2. It has the adjustable center bottom pin. But I don't want the insulated center pin problems to happen with the new Proteus when I finally get one.
Now I am careful with trying to not over tighten, but the problem is still there. I hope the Proteus will be made to handle or outdo this problem.
