FW: Space costs of dynamic fields?

Are there any extra costs for dynamic v.s. static fields? That is, if I have
the same dynamic field in 95% of my documents, should I just make it static
and empty in the other 5%? Will query speed or change? Which choice will use
more pace?
 
Otherwise, the only downside of dynamic fields is that you can't say, "give
me fields a*_t but not b*_t" in a query. I haven't found others in the mail
archives or the wiki.
 
Thanks,

We're gonna fix this one.  It's part of this issue for now:

I'd like wildcarding to be consistent whenever you can list fields.   
It can be handy to get all fields of a certain suffix back from  
facets or stored fields.
