Help on choosing a valid pattern: composite or not?

Hi to everyone,

I'm just writing a toy application using C# to make some
practice with Patterns and layers.

Now I'm faced with the "huge" dilemma of which pattern best
suits the object oriented world I'm building.

I have one object which represents a net, whose node
can either be:
1. A net
2. A proper node (of various kinds; Factories?!)

Both the "node" and the "net" have similarities in their
interfaces.

For example:
Net:
- Add a node
- Delete a node
- Execute a node


Node:
- Link to node (Could be translated as: Add a link to a node)
- Unlink to node (Could be translated as: Delete a link to a node)
- Execute

Node have some properties that Net doesn't have, and the
clients are expected to deal with them.

If it's possible, I would like to implement clients so that
they shouldn't have to care about the difference between "nodes" and "nets".

Without taking into account the "properties" aforementioned, from the GoF book I understand that the "Composite" pattern would be the
route to take.

The question is, is still "Composite" a good pattern to use
if those "properties" are to be considered from a client
stand point?

Thanks in advance for your help.
Regards,
Carmine
