Thanks Matt .. read the article on page 12, most of it talked about post 1995 17s while mine is pre-1995. I do have the older Sport equipped with HARKEN main traveler track (as mentioned in the mag and do have the new sail already.. it says that I may(?) need to convert to the class legal 'Tracker' travel system (not included).. I'm not at the point of needing to be 'legal' so I guess what you and the mag while not talking directly to my unique situation is that because I have the new sail, I need to convert away from the old pre-1995 crew traveler to the post-1995 Sport 'Boomlet' Sail Foot ..
Thanks again for your opinion,, do appreciate hearing from other sailors.
