I had the same issue in earlier days.
Initially,when I started collecting fountain pens,I like those really smooth nibs,those super super smooth ones,like most people do.
One of my favorite pens at that time was the TWSBI 580.
And then I started liking pens with some feedback. I found Jowo and Pilot pens(In general) to be too smooth for my like.
I even prefer the pilot metropolitan over the capless just because it's more feedbacky.
I tried to use micro-meshes to make some of my nibs feedbacky.
But after a few days, the nib becomes "slippy" again.
Then I realized that the feedback was created by the tipping material.
Some nibs are smoother,some are more feedbacky.It all depends of the material of the tipping.
Whereas the scrachi-ness(Sorry for my english,I don't know how to spell this word) was created by the shape of the tipping.
If a pen is well polished,it should not be scratchy. But It's possible that It's feedbacky.Don't get confused because of that.
I've yet found the way to create feedback,sorry about that.
All I can say is,don't buy Pilot,Jowo(Including TWSBI,Franklin-Christoph,Edison) nibs.
I also like the feedback of a Bock nib(Kaweco nibs are made by Peter Bock AG),and I know a website for buying bock nibs called standbond europa.
If you like feedbacky pens,you can try Shaeffer,Omas,Visconti,Delta,Conway Stweard,Faber-Castell pens which the nibs are made by Bock.
Or you can try Platinum and Sailor pens. I personally prefer Sailor. The hero 100 after about 2-3 weeks of smoothing is pretty nice as well(if you like finer nibs).
Hope this was helpful.
