Vertigo, the Lamy pencils I have sound the same regardless of the presence or absence of lead. I wonder if the noise you hear is from the lead. I use Pentel or Staedtler B in mine. They're not silent when I advance the lead, but they're smooth. Maybe a bit noiser than a Pilot and a Rotring I have lying around. Perhaps this is your oft-noted sensitivity to high frequencies!
If you like heavy pens, you should try Dupont. Expensive, but very nicely made. You'll look like Arnold S. after a while. You need his arms to write with them, and his bankroll to afford them!
Gergor, there are now four kinds of ink/refills other than fountain pen ink. First we had ballpoint refills; the ink in these is a paste, spread by a captured stippled tungsten ball in the tip of the refill. The Parker design size and shape became a "standard" refill, and is now a DIN (German industrial) standard. Most German and Italian refills are made by Schmidt, in Germany. Of course many manufacturers have their own size and shape for refills; I like the Cross jumbo refills for their Selectip designs (the refill is made by Schmidt). Parker's latest ballpoint refill is perhaps the smoothest writing; these are marked "improved" and are made in England. The medium blue is quite nice to use and writes effortlessly (for a ballpoint). Aurora's blue refill is nice, too. Blue ballpoint refills usually write smoother than the black ones, in every manufacturer's lineup. You have to be careful in interchanging the "standard" refills because there are often slight differences between manufacturers sizing of the tip sleeve and the nosepiece hole. Sometimes if they're not exactly intended for the same tolerance you can get a bit of "rattling" when using the pen (the Parker make that noise in my Aurora pens).
Second, we got rollerball refills. These used a watery ink, sort of like fountain pen ink in an oversized ballpoint design. They run out fast, and dry up fast, needing to be capped. Then they made "capless" rollers, that didn't need to be capped; the pens retract the refill, like a ballpoint.
Third, they made gel refills. Most are replacements for rollerballs refills. The ink is a thick, high-viscosity gel, mid-way between the watery fountain pen ink and the paste ballpoint ink. The Pilot G2 pens have this kind of refill, but my favorites are the Cross and Aurora. Again, each manufacturer has a unique design (or two) for the refill, but some "standards" have emerged, and many of these are made in Germany by Schmidt or in Japan. Most high-quality rollerball or gel pens use the body size and shape of a fountain pen (it's more profitable). Black gel refills tend to be the smoothest, with the most solid line. Gels and rollerballs often come in .05 and .07 tips.
Fourth, two companies have come out with gel ink refills in the "standard" Parker shape, so you can put the gel ink refill in many ballpoint pens. Yafa has refills made for them, and Parker recently came out with their own. I've tried both. The Yafa I hated -- I thought were like fingerpaint -- they smeared and left uneven lines. But they make many colors. Parker's version is better, but I don't like them. I have not found the blue locally, but the black are appearing in the office supply discounters and even WalMart. They're not bad, but they still have that "fingerpaint" effect when I write with them. And I get blobs on the tips all the time. Some other manufacturers are making interchangeable rollerball and ballpoint refills for their own design pens.
If you want refills, the best place to buy on the web is the Ink Palette. Anne-Marie H. is the ink expert without peer.
