Hello there,If you are looking for a light twin, the Aerosoft DHC-6 Twin Otter is the way to go. It comes on skis, floats, and wheels, and is highly detailed and accurate in its flight dynamics and model. The VC is great, and it barely drops FPS. Definitely the way to go. For the BizJet, ©ommercial (L)evel (S)imulations have their own business jet, not sure what kind it is. I don't have it but it is supposedly good and low priced.Best Regards,Jon
