AWE and Fixed vs Dynamic Memory Allocation

Configuration question.

[woop01]

We just upgraded our server from 2 to 4 GB of RAM and we're trying to figure out the best way to configure the SQL memory allocation.

Server Specs

3 Ghz
4 GB RAM
Windows 2003
SQL Server 2000 Enterprise
AWE enabled
/3G switch on

Should we use a fixed or dynamic memory allocation? I've seen in some places that with the AWE option, you might as well used a fixed amount of memory for SQL server. In others they always recommend using the dynamic option.
