i would say in a jet its assumed you are IFR and so if you are VFR you should clarify other than that clearance to XXX works just fine. what are your guys thoughts on callsgin and squak only readback? On the ATIS at LAX it tells you to read back callsign and squak only, if its a clearance you are familiar with that you can give the controller before they give it to you (that gets a few chuckles) why waste everyones time reading back the whole thing? i dont wanna come across as cocky or anything by just reading back the squak. i apologize if that made no sense.
