I weigh about the same as you and bought a 152 SB recently. I like it a lot, and the magne traction is great. Its mid flex, so soft enough to play in the park but stiff enough to do everything else too. I dont do huge jumps or bomb blacks so I cant really give my opinion on that, but apparently the SB doesnt shine in those areas. Some places say that the pickle is the same board with a different sidecut, and some say its stiffer. I dont know which is the truth, but ive come to my own anecdotal conclusion from what ive read that they have the same stiffness.
NS = schwing!, for sure. Ive never ridden one so I dont know anything about them. There seems to be a lot of SB hate here, although it seems to mostly come from a few posters who somehow manage to find every skate banana thread. Everything I read/heard/watched about it before I bought it basically said it was an awesome board, but here the opinions were a bit different. Personal preference for sure, but I like mine and my riding checklist sounds similar to yours.
