I flew as a PIC in the CRJ at Mesa 2003-2005 before the 1500 hour rule. Then I left and went to NetJets which back then had a 2500 hour min. By 2007 I upgraded and could see a major difference in the quality of the F/O's I flew with. The young F/O's at Mesa with 500~ish hours had very little "air sense". They were great to do checkrides in the Sim with but had trouble judging the energy state of the jet on visual approaches. If they want to sharply reduce the hours requirement then they need to require training on par with what Navy and USAF pilots get.
