I basically use mlcc's for everything between 33n and 1u. But this is more because of cost as they are cheaper then box caps. And below 33n greenies are cheaper so greenies it is. I used to get up to 47n as greenies too, but they tended to be HUGE. So box caps they became. And now mlcc's.

agreed. i still prefer to use them when space is tight. the only issue i see is they seem to have short legs, well at least the ones i have do, so they won't make it across a bunch of rows.
If push came to shove I'd just solder some extra clipping to one of the legs to make them longer. Also, how come we sort of have OCD (thanks to |v|ark) against standup resistors but no OCD against caps that have to span insanely long distances? Personally I find the latter WAY more annoying then the former.
