This has all been covered before and the replies above give the flavour of our operation. The overiding point is "fly if you want to" - just be mindful of the weather/ATC mix and don't forget to ask your colleague if she/he minds. If you are hand flying a complex SID then the other one (PNF,NHP co-pilot er Dave!) is going to be busy on the RT and keeping the MCP selections up-to-date and monitoring your efforts
On the other hand, visual approach into simple destination and good weather then go for it - it's one of the reasons we do the job...........
