Amex Mileage Rewards - I believe that's 0.8 avios/point.
So with 170k you would have 136k avios.
AMS - KUL is 90k each way on MH, or FRA - DOH - KUL is 97,500 on QR. LHR - KUL is 105000.
AMS - KUL can also be done for 45k + £950 each way, and if you got two one-ways on points then you could probably get a cash fare back for much the same amount and earn some Avios in the process.
