One last point with the programming is that it'll put the exact same stuff on both bands. I actually prefer it this way, but on other dual band radios (Vx-7, etc.) you can have separate programming on the Main and Sub bands. On my FT-8800 mobile rig I tend to put all the repeaters on the left, and simplex on the right.. just makes it a little more intuitive, that's all.
So just know that if you have me dump the programming to your radio that you're going to have clones on both bands. Also know that from my experience if you attempt to modify one of the channels, that you'll potentially influence all of the other saved channels- that was my experience at least initially. I will test that theory later this week.
