That's pretty much what I figured. When I first started tinkering, going back a few years, I did a bunch of reading about using grigris for self belay and my memory is that the "death mod" was simply to allow better feeding of the rope through. I never got a clear explanation from websites/forums of why the chest harness was necessary but it seemed it was either (a) to orient the device to allow better feeding, or (b) to stop interference with the action of the lever (or some other grigri specific factor...like I say, I haven't used one).

Both the cinch and the sum have much straighter paths through the device (or so everyone says...not having used a grigri) so they feed very well. The cinch has a small unobtrusive lever, which makes it a pain in the arse to lower with, but is highly unlikely to jam open. The Sum doesn't have a lever as such, it is switched into descent mode by pressing a doodad (still trying to work out if this is a weak spot for roped solo).

m9: re lateral loading. I hadn't heard this but it does make sense. From just mucking around with the devices (cinch/sum) I can't see how it is an issue, but I'll go back and have another look!
