LayT, some day you need to become adventuresome, and get a nice two toned shading ink. Pelikan 4001, MB, Heribin and R&K..................you do need 90g or better paper to have the inks shade, outside the Rhodia 80g and some Japanese 70g. (I was late to the party with Rhodia, and got the new 90g instead of the regular 80g.)
I also had some good to better paper, in I did not find Rhodia or the Clarefontaine Triomphe 90g, to be overly slick...........I do notice it somewhat slick with butter smooth nibs. but not as slick as the reputation says. Most of my pens are good and smooth.....a slight tad of paper feel.
Toothy is like writing with a pencil.....those who like toothy, can talk of which #1, #3 or other pencil hardness they relate their nib and paper too. (Actually they don't...or not that I've stumbled on.) One does eventually need a toothy nib, so one can play with super wet inks.....or other dryer inks to see how a paper feels at it's 'max.'
I don't quite get into it that heavy.....but fountain pens is a land of extremes.
I grew up before butter smooth became IN........it's easier to make fat bloggy nibs butter smooth.
One of the reasons I like the 'new' 200's I have, they are good and smooth, the level under butter smooth. The same as my 400 and other Pelikan 90's pens.
My butter smooth 605 BB was swapped from a real nice M to wider BB in sooner or Later and it was much later I was either going to stub or CI it. I stubbed it to B or 1.0. It did have the baby bottom from over polishing, in many want butter smooth at all costs. Baby bottom is not common on the thinner pre'98 nibs, nor the 200's.
Shading takes a much better paper and ink match for semi-flex '50-65 era Pelikans due to ease of tine spread semi-flex is a wetter nib. It can be done, but is more work to find.
(other German companies like Geha made semi-flex to '70 or 72. I'm not sure when MB stopped making semi-flex. I think when the 146 grew in size. I have a '70's-80's Large 146 that has a regular flex nib. My '50-60's medium-large 146 has a real nice maxi-semi-flex nib.)
Many newer posters call two toned inks, 'wishy-washy' or pastel...........wanting a real wet line.
Well, I find vivid monotone supersaturated inks rather boring..............
Do lay hands on some 4001 Blue Black, one of the great inks, and it shades, on good to better paper. (It is illegal in the States, and has to be smuggled in, in small mailed packages.....they didn't use strong Norway Rats in the tests, so do not drink much of the ink. Pelikan 4001 inks shade on good 90g paper, ans is still cheap.
Pelikan designed it's nib and feed to that dry ink, which is why Pelikan is so wet with wet inks.
Oxford Optic 90g is a nice affordable paper. It is also used in the Red&Black notebooks. Clairefontaine Velout` 90g is exactly = to the Oxoford. I have both in spiral notebooks. Will buy again.
Your wide nibs will do well with sheen inks....but there I'm way behind, and don't know my A from my Elbow. Again good paper will be needed.
Writing is 1/3 nib width/flex, 1/3 paper and 1/3 ink, and in that order.
(Some folks add 1/3 user too.)
Do spend some time over in the paper section finding out what is the better papers you can get in Ireland.
