A mate of mine has stopped using DD 9512's as he kept killing them. His FI BTL's accepted the same power much better so maybe the DD's wont accept the power you are going to give them?
The atomic APXX will take over 10k easy, one of the guys from the uk was giving an apxx12 about 12k iirc and doing 158's few years back so they certainly will take power if you have the right spider config.
