Try this scramble: D' B2 R2 U B2 R2 U B2 R2 B2 D F D L2 U2 R D2 U F2 U F'
Time: 1:21.22
Total turns: 85
rotate the cube to my orientation: z2
Speffz for the cycles.
cycle edges:
A -> V -> D : y [D R2 D', M2] y'
A -> B -> T : U' L E2 L' U' L E2 L' U2
A -> I -> F : [M, U L' U']
A -> G -> M : S R2 (U perm: L U' L U L U L U' L' U' L2) R2 S' Obviously not optimal, but easy to execute. Optimal would be: x' [E2, R U' R'] x
A -> R -> W : L [M' D2 M, U] L' This is not optimal. Optimal would be: D L' D M2 D' L D M2 D2
A -> U -> H : y L2 U2 L E2 L' U2 L E2 L y' This is not optimal. Optimal would be: y' x [E2, R U2 R'] x' y
cycle corners:
A -> C -> B : A perm (R2 B2 R F R' B2 R F' R)
A -> W -> S : R2 U2 R' D2 R U2 R' D2 R'
A -> G -> D : [L D L', U']

@Mike: Now that I'm reconstructing solves, I see that I don't use BH edges on 3x3x3 every cycle. There do seem to be some cases where I just do what feels fast at the time, even though I know that it's sub-optimal. For 3x3x3 I'm starting to see that this is probably the better choice. Of course I try to use mostly optimal stuff on 5x5x5 and 7x7x7, but after looking at my solve reconstructions I definitely don't on some cycles. The Speffz central edge cycle A -> U -> H I would definitely do sub-optimally as a 9 mover even on the larger cubes. I feel the 9 mover is more "comfortable" with fewer cube rotations I guess. Again with the foot in the mouth for me.
@Ralph: No worries on the movecount for Old Pochmann. Trust me that most of us are already convinced that it is a fast BLD method. I would say not to count your overall movecount, but maybe your setup moves movecount, just to make sure you're always using the most efficient setup moves? We all know the premise behind the method, so that repeated use of the T perm or whatever PLL you're using (R, etc.) shouldn't drag down your results here. Try a movecount without counting any of the T perms, then tell us how many cycles you did. That would give us an idea of your setup turns per cycle, which could be useful information to know for Old Pochmann.

Ok Aron, Mike, Ralph, those reconstructing solves here's one more. This solve was REALLY fast for me, like holy crap!
