I've bought all my F-C pens at pen shows where they personally set up and tune the pen for you. I have:
- Model 20 Marrietta with #6 fine steel nib
- Model 65 Stablis with #5 steel Masuyama fine cursive italic
- Model 45 XLV pocket pen with #5 steel Masuyama fine cursive italic
- Model 02 Intrinsic with #6 steel Masuyama fine cursive italic
All four pens write perfectly without skipping or drying. I use mostly Noodler's inks, but the Franklin Christoph inks are very nice and well-behaved, if not water resistant. I think that F-C pen designs with the thread further up the section helps ensure a tighter seal and less area exposed to air when capped.
My favorite of the four is the Model 65 with the #5 nib. It is a joy to use. I prefer the #5 nibs to the #6 because I like a smaller profile and finer line. Mike Masuyama is a master of turning a fine nib into a perfect cursive italic. I now only buy his nibs on the new pens, although I have tested their SIG nibs and like them.
The Model 20 is a slip on cap that is strictly friction fit. It seals very well, but frequent uncapping and recapping sometimes causes pressure changes and ink burping. The 45 is a small pen that only uses the small international cartridge which I refill using a syringe. The 65 is a desk pen and doesn't have a clip, but I carry it in my pocket anyway. The Model 02 is a bit larger and, with the #6 nib, is the biggest of the four.
I write mostly on Black n' Red, Quo Vadis, and 28# Staples laser paper. These nibs work just fine on these papers, but it always depends on the ink you pair with the pen.
I've gotten great results using DeAtramentis Document Blue, Black, and Dark Blue ink in the Model 65 with the fine CI. Just wet enough to write smoothly, but not bleed through like DA Doc inks tend to do.
The Model 45 with fine CI pairs beautifully with Noodler's Zhivago for a nice, fine line.
