Dear Jens,
No, I haven't noticed any odd gear-tooth problems, but my opinion on the matter is probably
worthless. I use ancient friction shifters and only a few gears. Even worse, they're 7-speed
cassettes, of which I have a fair number of spares.
Probably 80% of my riding is done in 53 x 11. Most of the rest is done in 39 x whatever the second
largest rear cog is, sometimes the third. My daily 15-mile ride is, from what I gather, peculiar,
but extremely pleasant.
I do notice, however, that Shimano rear cogs have various indents, scallops, and minor carvings
intended to help the chain shift. Possibly you have some kind of chain mis-match? I don't know
enough about this to say anything helpful, but luckily there are an awful lot of remarkably
knowledgeable and helpful fellows just aching to see questions like this.
Good luck,
Carl Fogel
