My first bundle I purchased was T-Racks deluxe edition. Very cool vintage stuff in there. Last year I purchased Izotope Ozone 5. It came with a free upgrade for Ozone 6. Surprisingly they are 2 separate plugins and I gotta say, I use Ozone 5 more than Ozone 6. It seems easier to use with much less latency and CPU usage. I use a couple free Massey plug ins that are real simple to use and sound great. And last but not least, the stock Protools plugins that probably get used the most.
