I hope 100 fields isn't a problem, I have one that is about to get
converted that is just over 300 fields, although some of those will
get dropped allong the way. I still expect that it will be pushing
past 250!

If 100 works, then other then the fact that a record is likely to be
multiple pages, it's not worth spliting it into pieces, and
complicating the application, just to reduce the field count,
especially if you need to be able to handle it as a single unit.
