Still fail to see your logic. Even a G1000 guy trains partial panel on standby instruments. Probably more often than a 121 guy in a glass cockpit. When was the last time you flew solely on standby instruments in a crj? It doesn't happen. You can start out training in whatever you want, most guys don't start on glass. If anything,the guys in a G1000 training environment with a couple hundred hours would have the edge of the guy dusting crops for 3 years vfr.
