Which do you think is more efficient? "ground, N12345" ..... "N12345 ground" ...... "Ground N12345 is at FBO VFR eastbound ready to taxi with information charlie" ..... "N12345 runway 24 taxi via..." OR "ground N13455 at FBO VFR eastbound ready to taxi information charlie" .... "N12345 runway 24 taxi via..."

Same thing on RADAR. give me something to work with (but keep it short) instead of a required extra transmission. A basic request such as taxi VFR or request flight following with call sign will do. I may ignore you on the radio at first, but I can start computer entries on you while I'm talking to another aircraft or coordinating something with another controller. PLEASE use your callsign when you readback or acknwowledge a clearance. I may recognize your voice but the quality control folks (and lawyers) that listen to tapes don't. Also if the clearance involves a runway and or hold short instruction READ IT BACK or else I am required to get you to do it.
