I have flown countless times to Asia for 120k in F (and also added SIN-SYD-SIN in F for another 20k AP miles). If OP wants to fly from North Ameria to SE Asia, it's 100K in biz and 120k in first. OP can fly to any of the following destinations for the above mileage redemption on Aeroplan - Thailand, Singapore, Taiwan, Vietnam, Korea, Japan, China and Hong Kong.

The 130k/170k you have mentioned is to Brunei, Guam, Indonesia, Cambodia, Laos, Mayanmar, Mongolia, Macau, Malaysia, Phillipines, East Russia or Saipan.

As you can see the more popular destinations are for 100k/120k. OP can easily get a cheap inter-Asia flight to any of these destinations that require higher mileage and save the extra 30k/50k mileage.
