I'm running TRS12 with NO patches. I have what I think is a high end system and I'm happy with the way things are running. NO major problems. I see no problems being able to run TANE. I've seen a few routes being developed that require SP1 so I got to thinking do I really want o patch to SP1? If I do patch what can I expect? I really don't want to be fixing a bunch of items or not be able to use items that I already have running. I'm thinking that maybe I should wait until TANE arrives sometime in December. What are the pros and cons of patching to SP1? Thanks for any input you may have.
