I spent years with reel to reel machines and then ADATs. I'll definitely keep Pro Tools. I am too spoiled with random access editing, no loss bounce/copy, a lovely lack of required maintenance, having to buy tape, etc etc.
Although I've heard of people tracking on tape and then transferring to Pro Tools. Or more commonly tracking on Pro tools and then mastering to a 1/2" half track at 30ips.
Whatever keeps the creative juices flowing
