Flown them on several occasions(2),never had any issues.Ive taken the time to engage the Captain in conversation,have found both very pleasant,knowledgable and proficient.On both occasions I've introduced my self as a fellow pilot,and been offered a headset etc.Actually felt they were quite professional for operation they were running.Takaka to welly.In conversation with one young fella,he was definitely building time,and since I had flown this type of operation many years ago,he knew what he was doing
