If you've read that thread, then you know all the dangers associated with feeding live. I think feeding live is perfectly acceptable if you find it more convenient and take necessary precautions. You should stay in the room with the snake until the rodent is dead, and have tongs or hemostats ready to intervene if something happens. Just understand that risks are involved, and there are ways to prevent them.
People smoke, don't wear their seatbelts, and do lots of other stupid things to endanger their lives. You can't protect everyone from everything. As long as you are making an informed decision, and go about feeding whatever you decide appropriately, then whatever you decide is fine.
However, you might want to try Frozen just for an experiment. You just might find it more convenient than you think!
