I've had a note on my desk to ask on Flyertalk if keeping the Chase Sapphire Preferred is still as 'lucrative' as it used to be--since the earning-benefit reductions that began Jan. 1, 2015.

After reading part of this thread, I am kind of coming to the conclusion that there may be better deals out there.

A couple of questions:

1) If I close my CSP, will I lose all the earned points that I haven't used?
2) Which flyertalk forum/thread would best for me to ask about which card I should apply for if I cancel my CSP and would like one card to put my ~$25K annual spend?

Thank you.
