I think they are good, but I also think you don't want to go way over your DL # due to possibly snatching with your back off of the rack. You are less likely to put this same type of strain (the snatch) in the middle of a full dead lift. If you snatch on a deadlift, your legs will absorb some and your back won't feel the full brunt of it.
Get yo' minds out of the gutter....not that kind of snatch.
