For park, center mounted is the only way to go IMO, even with asymmetrical skis. Bindings are super important and definitely make a difference. Better bindings have more metal and are thus heavier. Weight makes no difference except on your shoulder... That said, someone who is light and/or not a very aggressive skier won't need an 18 DIN binding. However, it wouldn't be a good idea for a novice to get a shitty plastic binding, e.g. Marker Free 10's. For an absolute beginner or someone light, I'd go with either PX 12 or STH 12 Driver. As you progress or grow, step up to burlier bindings with more metal, i.e. PX15, FKS 140/180, STH 16, Jester Pro, etc. As far as boots go, GO TO A BOOTFITTER! The only good boot is a boot that fits, and you'll have no idea which boot that is unless you get properly fitted. Again, weight makes absolutely no difference. If you really think a few pounds here and there in your gear will significantly affect your skiing, you should probably spend some time in a gym...
Do you ever wanna, like, look at a chick and bare your teeth? You know, like a chimpanzee?
so a forward spinning flippy would be a blunt?
Your momentum is wrong.
