jib size
Carl, I too had to decide on the size jib I wanted when selecting a 36 jib an now a jib for a 42. You need to think about where you sail and if you race etc. The thing that made me go for the 155% is the fact that I can ALWAYS use it on calm/light wind days and it cost more. So, if you can get the 155 for the same price, that would be my selection and then get a second sail for less $$$$... good luck!
