My honest opinion. I've held a few G&Gs. CMs just feel all wobbly, I held someone's top tech G&G and that felt a bit better, but once you get into that price range go with any VFC. The self-shimming gears are not THAT big of an issue. Both of my VFCs still have their self-shimming gears. The one noticeable difference I've found is the gearbox tends to be a tad noisier. If you go VFC just stick with the stock gears until something fails. You'd be ripping out at 90% good system to put in at 99% good system, or at least that's the way I look at it.
I'll definitly change the gears in the future, but for now they work just fine for me.
