So at this point it is definitely more beneficial to redeem e-Rewards dollars for A+ Rewards Credits over Rapid Rewards Points. The $50 redemption is for 1000 RR points or 1 A+ credit. Since 1 A+ credit will be converted to 1200 RR points you gain 200 points (arbitrage). While it's not a big difference, I have a decent e-Rewards balance that I'll now empty out over the next few months.
