Organisation of filters, pools, etc

I would like to hear from others as to how they use filters efficiently. I have 
just stumbled on my own system, and realised that I must have been doing it all 
wrong up until now.

This is roughly how I work, and I would welcome any advice on how to improve 
the organisation of my RSE :

1. For each job I'm working on, I create a new connection. When I start the 
connection, a standard CLP that is in every developpement library puts the 
library list in place. That way, as soon as I start work, my *CURLIB is the 
development library.

2. When the new connection is created, I can see a filter pool that is common 
to all connections. I'm not sure about how that works, so any ideas would be 
great.

3. In this "default" filter pool I have filters based on the *CURLIB. As I have 
standardised programmes for installing and testing my modifications, I have 
managed to greatly reduce the number of filters I need to create. 


Can anyone improve on this ?
Can anyone elaborate on the use of filter pools ? With examples ?

When I click right +  new on iseries objects, under filter pool is "filter pool 
reference". If I choose this, the menu proposes a list of profiles. What 
exactly is this filter pool reference?
