So... I thought I'd do a bit of a comparison last night. Took the Omega wagon out but drove it in full manual mode. Taking just about driveability and shift feel, I guess it's acceptable, but only just. With some tweaks on the line pressure it's not too bad combined with some VVT tweaks it's not bad for a 3.0L. I guess with some more work, the shift feel might be improved more, but it'd still never match a manual for driver experience.
