With the Vac 700r being released soon I am wondering if I should get that or the Vac Mini. I expect the nibs for the Vac Mini to be more like what I am used to with the ECO. The larger nib on the 700 from all reports would write a little wider. I expect getting a F or EF in the 700 would be fine, but the 1.1 stub might be too wide for my writing style. If I get the Mini I think I will order the 1.1 stub. I like it a lot on my ECO.
Other then line width. I wonder if one is more comfortable to write with then the other. The step down on the 700 seems to be bigger. The grip/section diameter is almost the same 10.0mm vs 10.1mm. I am not sure I would the difference.
I normally don't post my pens. I expect I could use the Vac Mini unposted and could always post if I had to. Its not that much shorter then my Pelikan M215. The 700r would be just fine unposted. I like the looks of the 700. It seems to have a nice gradual taper in the body from the section to the tail.
The size of the Vac Mini would be a better pocket fit of the two. But that would only matter for a shirt pocket.
I guess the biggest decider would be knowing how comfortable people think the two are in hand. I have medium size hands.
