Appearance & Design (10/10) - I am a bit biased; I bought this pen specifically because I loved the look. I was concerned about the size and heft though, and once I got this pen in my hot little hands, that concern evaporated. It's much lighter than I thought it would be and actually feels ever so slightly smaller than my Wall Street LE.
In terms of design, there is one shining thing I love about this pen - the twist cap. It locks tightly and will not pull of, but it only requires a quarter turn to open it. I have mostly twist cap pens and sometimes when I'm in a rush, I find all the twisting takes up too much time and can feel onerous. I absolutely LOVE the cap on the Homo Sapien.
Nib & Performance (10/10) - I liked the idea of a silver Homo Sapien, but the nib it comes with is actually the same two toned palladium one you get with the Wall Street LE. I asked Bryant to switch the nib for me to an all silver one simply to maintain the symmetry of the silver trim. I think it looks great!
You cannot go wrong with the Visconti palladium nibs. They write smoothly and deliciously, like silk. One thing to note is that this nib definitely runs wide. The medium on this is about halfway between a medium and broad in Pelikan nibs. That doesn't bother me, but it is something to consider when choosing the nib. For comparison, here's a shot of the index of my ink journal (from a while ago); the Fuyu-Gaki was written with a Pelikan m625 in medium, and the Asa-gao was written with the Wall Street palladium nib in medium (which is the same nib as on the Homo Sapien). Notice that the Pelikan line is just slightly thinner.
Filling System & Maintenance (9/10) – The Homo Sapien is a power filler, which has it's good and bad points. It can be kind of a pain to fill the pen completely, but is still manageable to do *IF* you can see the ink level. However, this gorgeous pen has no ink window, so I find it difficult to figure out how much ink is loaded into the pen when I'm trying to fill it. Generally this isn't a problem for me because I like to change inks frequently and I always carry three pens, so I'm never stuck running out and I don't mind if it doesn't fill completely. But if either of those are an issue for you, consider yourself warned!
Cost & Value (9/10) – This is always such a subjective topic. I honestly cannot even remember what I paid for this pen, but I think it was about $700 USD. I do not regret getting this pen at all, but let's be serious - in terms of writing, I get an equally happy experience from my Pelikan m625, or even my TWSBI with an m425 nib on it. I think that if you like the look of the regular Homo Sapien but prefer silver detailing, getting this pen is totally worth it. It is a pen I use every other time I change inks, which says a lot about what a great pen this is (given how many I have!).
