I'm like to practice manual flying to keep my skills current, but I think there is a time and a place for it,
The 737 series all have a CWS autopilot mode. If people are a bit apprehensive of manual flying due rusty skills then simply leave the AP in CWS and hand fly through the autopilot. That way, you can whip into full automation mode quick as a flash, if you feel you can't hack it in CWS
