Since this is a question about the best miles redemption (and was nothing to do with a Mileage Run Deal) I've moved it to MilesBuzz! forum in case anyone has some info regarding the relative values of the various miles shops.
Since there are already some tips, there is probably no need to move this to a FFP program, since it's nothing to do with the MR or FFPs, except for the relative attractiveness of redemption rates.
Thanks for the MR Deals RBPs!
