HKG <> TPE x 8 = 8,000 CM & 16 CS
HKG <> US x 1 = 15,000 CM & 2 CS
SL MPC = 30,000 CM or 20 CS

U still short of 2 CS even if OP willing to pay DOUBLE fare as follow:

HKG <> TPE cheapest CX fare HK$1,200
but cheapest fare can earn CM/CS $2,400 ( it's a double.)

HKG <> US cheapest CX fare HK$6,060
but cheapest fare can earn CM/CS $11,600 ( it's almost a double.)

Are you willing to pay DOUBLE to get SL MPC?
