I know there are multiple ways to handle updating msi based apps with msp based patched via ZCM. I am looking for what works best for people that are further along in larger deployments than we are.

As a specific example, lets take Adobe Reader 9.3.x.... We deployed 9.3.3 originally using the stock msi and msps from Adobe originally and a custom transform. This worked just fine and continues to. Now, 9.3.4 is out and it is just an additional msp.

So what works best? Anything like the following:?

Just add another install condition for the new msp and rev the bundle?
Create a bundle group with the base app and a new msp app?
Am I missing something even more simple?

We are looking for the lowest impact method to the users and network.
