I am glad that you have the same concern which I have. I am about 150 lbs, beginner and I went to nearby shop to buy ride DH 153 or Twin 151. However, the shop guy recommended me to buy 155 because I might go out of park and then I might need longer one for better stability. I agreed and I bought ride DH 155.
But like you, after reading some posts on here and there, I am also worried about the length, because people used to recommend 151 ~ 153 for my size.
What I know one thing is that the reason why I am worried is because I am a biginner. Here, I really don't know what to do. The shop guy might be right.
