Greetings from Singapore!
I found this community by accident and I am glad! I am just starting out with this and would certainly be poring over every resource and tips provided here.
I own now 2 Kaweco sports, 1 dip pen (brause 66 extra fine), 1 pilot parallel, 1 bottle of Parker Quink black ink and 1 Rhodia writing pad - a humble collection.
Re brause 66 extra fine, I find the upstrokes rough. Is it a user problem, ink, paper or nib problem? I have watched videos of people doing well with brause 66ef. If the problem is with the nib, then I am happy to buy something else to try as I plan to also invest in an oblique pen holder.
I am now contemplating brush pens. I tested Pentel brush pens last Sat in a bookshop - its hairs have already strayed from the abuse it received from multiple testers. Are strayed hairs evitable with proper care and use?
