I think it's best to open using power surge slightly before the pull, when the tanks pull macro is at 1s is best. Then:
PS > (tank pulls) HT > BFB > ID > IR > DIS > X-pot > CT > jump > PH > Sweep > TT > DFD > VT > LS > FT > SSD (IR falls off after SSD, BFB/x-pot after next gcd)
This opener ensures that BFB/IR/xpot are up for all the weaved in oGCD's. Also prevent any slight delays from using 2 ogcd together
