I switched to a QS recently too upgraded from a platinum
Congrats! That was a good choice, The platinum card is a good starter but useless beyond that. If your looking to add a second card I would wait a bit and try for a Discover card. They are pretty relaxed on new files and a pretty good card to have.
Sorry, You stated Cap1 was your first card so I assumed it was your only one.
