Personal view is to use external rpt files.
Advantages
1)You can provide custom alternate rpts for your clients
2) A small change to rpt doesn't require a recompile and redistribute of your exe
Disadvanatges
1) lots of extra rpt files to distrubute
2) Your report design is wide open for anyone to borrow of change
Using the DSR: advantages
1) Fewer files to distribute
2) Rpts are securely locked inside the EXE
Disadvantages:
1) Change your report spec, send out a new EXE
2) Everone gets the same reports. Difficult to customsie reports. Editor and Publisher of Crystal Clear

If you want secure reports, then you need to use the DSR file.
But your reason for wanting "secure" reports needs more thought. It is easy enough to check for the existence of a rpt file before you assign it to the RDC objects. And you might have a reason you want your user to create a variation of one of your standard reports.
Another way to secure your reports is to make them all ADO, so they can only be used via your app passing it the data it needs via an ADO recordset. Editor and Publisher of Crystal Clear

We chose to use all .rpt files.
Two reasons drove this decision. The first was a VB limitation (solved, I believe, by the latest VB Service Pack and MDAC 2.5). The other is a desire to be able to update/change a report without having to reinstall the application.
We have 5-600 users and a system locked down so only adminstrators can install software. A nightmare when only changing a report.
To help secure the report files, we loaded them on a network drive as read-only and the directory is network-secured as read-only for all but the development team.
good luck
