It's a little annoying the co-pay waiver has zero impact on Tango.
For anyone below SE, Flex to J is $750, and Tango to J is $850. Upgrades are no longer an incentive for buying Flex.
But for SE, there's still a HUGE incentive to buy Flex, because it's $0 instead of $850.
Why not just have some blanket policy like save $500 on TATL co-pay, $750 on TPAC co-pay, and $200 (?) on North American (I made up the last number since there is no co-pay for anyone else in Flex).
