M_Boats: Working Jib

Hi, I just replaced my original working jib with one made by Ullman sails. It came in with a deeper foot but not nearly as much material along the leach line. I have been told that if I install jib tracks on the cabin deck that I will have more power and more control over using my old system of using the aluminum toe rails with pulleys. I am trying to decide whether to have a larger sail cut or to install the tracks, pullys, cleats. I would welcome suggestions. What is the size of the original working jib? I had thought it was a 152 but have been told 109. Randy M-17 "Fore Play" Bearlake, Utah
