You probably want some combo. We use mod 3 for paging - the more devices the better under heavy paging load. Mod 1's would be good too -we did that when we were on a HDS box that had little bits of leftovers somehow.
Mod 9 and 27 for everything else Linux. My preference now is the 27 as there is just less of things to define (both to guests that need LVM'd bigger filesystems) and to VM and VM:Secure (our directory manager). Mod 54 has some restrictions with minidisk cache - so you might want to avoid those. And FCP, like David mentioned, we're working on that for the crazy applications that want 2TB defined to a single Linux. Make sure your disaster recovery system/provider can do whatever you decide.

The point of interest is which model provides the least amount of 'wasted' space due to overhead requirements. Here is a chart that I've cobled together from a few web sites and you'll notice that the usable bytes column is empty.
