The stock rig is not durable enough, and I'd rather have an outhaul that I don't need to worry about. At our regatta 2 infusions sliced through the spectra outhaul 3 times. Granted, it was blowing 25 the first day. Suffice it to say that I will be changing mine as soon as I figure out the best mod. I have never seen th old system. Can somebody hip me to the design?
