This is an interesting thread for me because I'm in exactly the same position; looking to move to a 120 in the Spring. As a dedicated petrol head, I generally prefer speed and handling over comfort, but in this case the benefits of the 120 outweigh the disadvantages. I've spoken to several owners and none of them have any regrets. C of G was an issue in the early models, with the battery
I can't agree with the Gazelle argument though - it's a completely different ship. As a petrol head I love it, even though the stretch is still cramped in the back and can be a pain to fly, but it's no comparison to the 120. Also, check out insurance. Haywards' quote was ridiculous for a G reg Gazelle, asking for a zillion hours on type, even more on turbines and a safety pilot at all times!!! There have been a lot of gazelle accidents...
