I went from a Seneca to a Shorts and the jump at the time was big for me. Only then did I realise how much I didn't know about aviation. That's why it always amuses me when I hear of these 200hrs somethings wanting to go right into a large jet. You don't know what flying is yet.
All the hours I did were hand flown. Conversely, in a two hour flight you'll actually hand fly around 10-15 mins in a jet.
Recently I spoke with a low-hour chap who went straight into a G550. In four months he's flown 180hrs, of which only seven hours were hand flown.
What do you think will make you a better aviator? Go with your heart.
Good luck whatever you decide.
