I prefer the 6-shot versions, as the cylinder looks better IMO than with a 10-shot version. Same goes for a 8-shot model 63, which is not so good looking as the 6-shot old version. However, 6 or 7 on a 686/686+ have almost no 'visual' impact, but with more a gun looses it's classical look and seem like cheap stuff.

If it would be an unfluted cylinder, I would mind less. But maybe that's only me.
