I havent listened to Hadley for quite a while, but Brohman and Raaay used annoyed me the most. During the Athens Olympics, one week I listened to the show right through to the end and enjoyed it. The next week Hadley was back with the Vaudeville routine and I turned it over within half an hour.
Besides Hadley, Gavin Robertson is the most annoying person on radio.
The next worst for me is MG, though he doesnt grate me that much on Saturday mornings on 2MMM. Keep MG away from making shockjock comments and hes not too bad. For me, Ray Warren seems to keep him away from blowing a head gasket with outrageous statements, like he used to do on 2SM when Graeme Hughes pulled his strings,
