IMHO, the Choice -> RR conversion is the one that's unreasonably generous and at risk of devaluation at the end of this year.
I agree. It sure is a great conversion rate...so you might as well max out the 20k AGR -> 100k Choice -> 40 RR while you can.
What other ways can you convert directly to Choice? Also, dose Choice have a cap on how many points can move to RR in a calendar year?
