Rollback segment size

Our database was created with 4 rollback segments with initial and next extent size of 128K.
I've noticed that highwater mark on them is approaching 30 MB and one just hit max extents limit.

In our case, seems like 128K for next extent is rather small.

Could I make it as large as 1MB or is that generally too large for a rollback segment?

Also, is settting unlimited extents on rollback a good or bad idea?
