I do like avinations physics contributions quite a lot. I was there yesterday with Judy @ her Hobo Park and her eeeeek [yes, it is 5 e's and if you misspell it she will go all bonkers on ya!!--i joke, of course] ride was by far the smoothest than in ANY other grid I have tried it on.
And just my usual reality check here, inwz physx thing is not fully implemented yet, and who really knows how good it will actually be if, or when, that happens...jus' sayin'-))
