I got a new skateboard, and I did ok on. But when my girlfriend (who has skatin a few years now) a bit trying, "he said, the trucks will be waaaaaay to lose and he could hardly do any tricks on it. Then he borrowed my board, exacerbate the truck, and went a bit, say it is good. I tried later, and the problem is that I could barely run, and it felt very uncomfortable. Should I do this or should I resolve to get used again? Help!

There are so many skateboard trucks out there. But that's not why I need help, I need it all. Is a lo-rise, mid-rise, 7, 5S, 5 0s ETC. I need to know what size is the best I want a skateboard. Is it better if you have less cars?
