Hmm. Thought I responded. Guess not. Okay-Let's start with the idea of breaking in a nib. Doesn't really happen. Sometimes the feed (the bit with the grooves the nib sits on) will have oil or fiber bits in it and that can slow flow or cause starts and stops. If there is enough of a wad of fiber in the tines you can get flooding, but it is fairly obvious it is there.
Some terms; spider web edges are usually referred to as "feathering" but FP users. When the ink is visible on the other side is "show through". When the ink goes through is "bleeding" or "bleed through".
Feathering has a lot to do with the paper quality. Sounds like the paper may just be thin. Try the pen on good copy paper, a small Rhodia notepad, and some Staples bagasse paper (sugar cane fiber). This will give you a good idea of pen vs. paper issues.
For great notepads and planners that a totally fountain pen friendly I like Gallery Leather. The notebooks, last I checked, are made in the USA (Maine). I love the ones the same size as a checkbook, which also come as a planner. See here-
So-are you an over-writer (hand above the line and hooking) or do you drag the hand through the ink, or an underwriter. I used to drag through the line but taught myself to be an underwriter. Makes things a lot easier with a FP. The "too much...too little" ink may result from uneven pressure of your hand while writing. Try to ensure easy pressure. Which leads to asking what size nib are you using? Should be a letter on the nib face- Fine, Medium, Broad. Sometimes EF for Extra Fine. How big do you write? Montblanc inks tend to be pretty "dry" writing, so there are a few factors to consider; the daytimer paper may just not be conducive to FP ink. Your pen may be a "wet" writer" (for which there is not a lot to be done), or you could have sprung tines. (Did you push hard and wind up with a gap between the tines?) If you can get a good close photo to post that would help. That said, there are nib workers you can contact who can "tune" the nib, or even alter the size. If the nib is the issue, you can frequently find Townsends with good nibs for not much money, and then you could swap in the nib, or just trade the entire section (area for gripping, nib, and feed) as they are all the same. The trim ring might be a different color, or make sure you get one with the right colored trim.
Re inks- if you go to Goulet Pens- http://www.gouletpens.com/-they have some cool tools for checking out inks, plus you can buy samples to test out. Really the only way to fly. And they are great with customer service. Call them show them the link to the blue, and they can probably recommend some inks. To my eye, right off the bat, I would say look at Private Reserve, DC Supershow and Electric Blue. Look at Diamine Sapphire and Sargasso, Noodlers Blue, Aurora Blue. There are, however, a looot of inks out there now.
A couple sites- Pentrace - newpentrace.com/mboard.html - a fairly quiet board these days, but nice because all the info is on one page, not divvied up in a bazillion forums like FPN (Fountain Pen Network - http://www.fountainp...work.com/forum/ . FPN can be a bit overwhelming (it is an offshoot of Pentrace that became a monster) at first, and you might get better answers to your questions quicker on PT as everyone who stops in sees the question. I am on both with the same handle.
Anyway, this ought to be enough to start you on. Hope it is comprehensible.
