M_Boats: Monty 15 Sails

Although I have sailed for years, I have never purchased a new suit of sails. I am highly confused by the plethora of lofts available when Googled. So, for day sailing, inland lakes and near shore Great Lakes sailing, I believe I do not need the finest/most expensive sails available. I am looking for value - quality sails, suited to my usage, at a fair/reasonable price. But, what cloth weight, loft, etc.?? I am located in MI if that's important. I am asking your input. Perhaps, if you have strong negatives toward any lofts, it might be best to privately email me. I thank you in advance for your anticipated wise consul. Fr. Jeff
