I'm not sure i can answer the exact changes, all i can tell you is that either way is viable and workable. I recently did a parse w/ another FC DRG of mine, 6 minutes long. He is Crit/DET and i was SS... he came out about 10dps higher, cuz i forgot my jumps O.o so, i'm not sure that by changing you will find it worthwhile or even a noticeable change in dps.
