Best slow-mo settings shooting 720p

I have a shoot this weekend where I will want some slow-motion shots and I'm trying to select my workflow.

I'll be shooting 720p on my HPX-500, so I can shoot 720pN24 at 60fps for built-in slow motion, or I can shoot 720p60 and conform to 24p later. Anybody have good reasons why one or the other is better quality?

This is a live event and I may only have the opportunity to shoot some things once, so shooting 720p60 would seem to give me more flexibility in post - allowing me to drop frames down to 24p or conform to 24p for slow motion. A drawback to this approach (besides the extra post time) is I'll be seeing a fluid 60p image and I'll have to remember to keep moves slow to avoid judder issues that I can't see (yet).

In this case, would I want to set the shutter to 1/48, since I intend to use everything at 24p?

Of course, I'll have a lot more run time shooting 720pN24 - but I'll have to set up a scene file to switch to slow motion and make those decisions on the fly, and anything I later wish was slow motion will have to be done in software.

Honestly I can do this either way, so once again, is there a perceived or proven quality difference between the two?

Thanks much!
