For sure, with age comes maturity for most people. My point was that regardless of age, if you are inexperienced then unfortunately you dont know how much you dont know, if you see what I mean.
The net result of that can be a low hour PPL with a shiny new MECIR that can be out of his depth weather decision wise. Most new CPLs are atleast under supervision by default having thier chief pilot or more experienced workmates to looking over thier shoulder and to fall back on for advice.
I dont know your postion but it may be that the Baron is privately owned and you will not have that back up or supervision from others more experienced than you.
The sad fact remains, PPLs in light twins are over-represented in the accident statistics around the world.
All the best.
