Right now I have a 69/170nm spring. I weigh in at 165. I live in Michigan where the roads are rough so, I am not sure if I am in the ballpark. LDH, I think you touched base on this with me a while back and I thought you told me to try it out first. I am getting a little impatient with our weather here in MI. We are having snow storm after snow storm. They are telling us to expect storms every other day. I am really missing the Niner!!!
