It seems that physicists need a complete barred MC encoding ?

Thanks for the pointer to CTAN:/fonts/greek/kelly, I will have a look at it
once I finished the more urgent things like moving to a new appartement etc.

I haven't had time to look at your MX proposal, but it might be a good idea.
It might at the same time alleviate rounding problems in MX1 which could
cause the gaps you have noticed in some delimiters. I have fiddled around
quite a lot with the heights and depths in MX1 to avoid rounding, but it
still occurs and metafont doesn't even tell you about it if the error is
below a certain size.

Thanks for these pointers, although I don't have the spare time right now.
