I've seen a Citation come in and go out of the grass strip at EGKR... just after it had been mowed and there was lose grass all over it.
It looked like it had been turfed itself after the very neat landing and the two-man crew seemed perfectly happy (not that they were the owners!)
I don't fly twins but I reckon my arrivals with planet earth are much smoother on grass than on tarmac. More forgiving, I reckon.
