The hot tip, IMO, is buy your twin and train in it.

That only works if you can get insurance for training in your plane. My
policy has a no instruction clause in it.:- Luckily my insurer treated the
time I spent getting my rating in a 310 as the time in type for the 340.

The no-instruction clause likely doesn't apply to the owner (at least
mine doesn't). But what I'm suggesting won't work for a turbo
pressurized twin anyway - both because the insurance won't buy off on
it and because you will tear up the engines in training.
