Which method is more effective? Wonder if it's CSR Roulette in both communication mediums. I'd prefer calling, but don't want to have to go through a PC to a Chase Sapphire, like another poster did, vs. going straight for the Freedom. Looking forward to getting my rotating quarterly multiplier categories in play again--that was fun.

Also don't want a CSR to mistakenly PC my pre-existing CSP down to a Freedom by accident.
