Inconsistency in feed/nib sizing, mainly feeds.
I really like the FPR feeds/nibs they are a great value but it seems there is marginal variations in the sizings of these products. It's not much, a decimal point or two here or there but unfortunately it's enough to sometimes make some combinations of feeds and nibs not fit snugly in the section of the pens that these are designed to fit in. Aside from that getting a better flex experience out of the box really isn't possible without these nibs and feeds, especially for this price point. If the tolerances could be a little more controlled it would be perfect. I was able to use 3 of the 5 feeds I recently purchased, the others fit but were too loose. This either provided a flow that was way way too wet or simply caused the feed to shift over time with the need to be straightened again and again. The others fit with good friction and requiring slight force, but stayed in place and allowed for a consistent fit/flow.
