A suggestion re "Ymdrechwn yn galetach." Back in 1965 the Avis Car Rental Company in the U.S. (and perhaps elsewhere) had as their slogan: "We try harder." They issued a number of lapel buttons at that time with translations into various languages. The Welsh buttons had: "Ymdrechwn yn galetach." The Irish buttons had: Taimid ag deanamh an-iarracht.
