I like practicing in actual but I'd stay away from that weather.
- 1/8SM and 200 in fog with 12/12 says to me that it could go

in a sec. I can practice misses under the hood.

IMO, flying under the hood and flying actual IMC are two different,
albeit similar experiences. However, the differences are such that I
believe there is simply no substitute for the real thing. This
statement is only meant to offer another opinion.

Additionally, I believe that practicing in actual low IMC to a real
missed when possible, assuming again that there is a suitable alternate
and proper fuel, is very important to the active instrument pilot,
since it may very well happen that an airport goes from "low to no"
during a real approach. A good example of low IMC going to below
minimums would be during lake effect snow season downwind of the Great
Lakes, something that is not always correctly forecasted.
