Mega form - more than 200 fields? It is reliable?

Mega form - more than 200 fields? It is reliable?

Hi all,


Please advice me on this:

I don't know what is better:

a) Create a Mega form, with kind of 200/250 fields, to work as single database, and create several stateless forms to feed it (On submit - INSERT TO). Then make several views to filter the information as i need.

Or,

b) Create several forms and register my data in independent forms, (but always have several commune fields).


What i intent do know is if it is reliable and fast to have a form with more than 200/250 fields. And the Pros&Con of solutions a) and b).


Another question is: Is it possible to rename the field at the side of the user?

Thanks!
