Don't worry about what people like and what is popular. If you like multi engines and sea planes, then that is what YOU like.

I see you have asked about sims and trainers in previous posts. Get a sim and a trainer. Practice and fly. Move to a second and maybe even a third plane, each a bit hotter than the last. Then look at getting a twinstar (multi engine) or even put floats on your original trainer to get a taste of what a sea plane might be like.

I didn't vote in the poll, like it matters one hoot, but I personally prefer to fly 2M aerobatic planes as I compete in pattern. But I greatly enjoy watching any of the planes you listed fly... even trainers.

Mindwarp... the witch and mower are cool, but those electic foamy boats that run on water, air, land rule. Now if they can get them to submerge and go into orbit, that would be awesome.
