The new G3 is very good. I've used the Ikarus Pro, is good also but the G3 is more realistic. It takes into consideration many things we don't think of like gravity, inertia, etc. The down side is it needs a high end computer to take advantage of all it can do. A P4 2.8(or equal) with 1Gig of Ram and a 256Mb video card. A 5200 works but a 5700 will run it without flicker with all options on, at any of the fling fields.
