330 seats
My feelings as well. Came back from Sri Lanka on one of their 330s - 12 hours Colombo to LHR.
The plane had Recaro seats so I can see why rally drivers go so fast - it's to get out the car before the backside numbness reaches the brain.
As luck would have it I drove from LHR to LGW to catch a Virgin 747 to Florida the next day so I managed to massage my rear end with 7 hours in one of their comfortable seats (even in economy).
Having flown in several other airlines 330s I think that Sri Lankan are the only ones - or if the others were using Recaro they've had them made to fit the human butt!
Happy flying
