>Can someone tell me on a general level is it bad to use updatable local views on large record sets (say 50,000) records. In my database which has stored procedures as well as referential integrity it seems to take forever to send the updates back to the table. Any ideas??

Views are generally a good idea for general application architecture, but can show their weakness when used on huge data sets. In operations on very large data sets where speed is a concern, you would probably be better served operating on the tables directly.
