I think that FSOne is an awesome sim for what it does and the models it has. That being said, unless some people can come up with tweaks, it isn't going anywhere until this fabled second installment of FSOne (please don't start the arguments again) comes out. As good as FSOne is, if there is an MSR on another sim, such as the pheonix sim now supported by Horizon, I would get that. I hear great things about phoenix sim as well.
