I have the 2014 Ultra Plus Pak. (I have bought that package for years.)

However, for 2015, wondering if buying the Plus Pak 2015 (non-ultra) would give me everything that is new for 2015 (added to what I have already in the 2014 Ultra Plus Pak), or do I have to buy the Ultra Plus Pak again to get everything?

If I bought the (non-ultra) Plus Pak 2015 to install over my Ultra Plus Pak 2014, what would I be missing (as compared to if I bought the Ultra Plus Pak for 2015.

Not to be looked at as a first time buyer purchasign one of those two packages--then there is clearly a huge difference. But for someone who already has Ultra 2014?

Thanks for the input.
