I have landed a PA28-180 with 35 kts X wind. The student on that trip who was an experienced PPL doing an IIMC course wanted to add about 15 kts, 5 for X-wind, 5 for granny and another 5 just in case. If he had continued at this speed he would have drifted off the very wide runway. With the correct speed and a slightly angled approach there was no problem at twice the demonstrated maximum using full flap.
