MB Ballpoint Pen - Which one?

[Covi101]

Gents,

Now that I have my Fountain Pen figured out and I already have theMEISTERSTÜCK PLATINUM-COATED CLASSIQUE ROLLERBALL. I want a MB Ballpoint. I want something a little bigger and different than my classic MB Rollerball. Below are few options I'm thinking about, in the order of my top pics, any advice or thoughts are welcome! Thank you!
