The general "consensus" is compromise equals loosing on both sides of the coin - always.
Pads are so stinking simple to swap in/out on 9x6 and 9x7 platforms you should keep street pads for street and get a dedicated set of track pads like PFC for DE. Not to mention you WILL bleed your brakes before each DE and will therefore already be "in there".
Brakes are one of two things one shouldn't compromise on... ESPECIALLY for HPDE in any run group above novice.
Good luck
