Jib Track Placement

[Fourwinds]

I am looking to install t-track for my 135% genoa and I am looking for advice on placement of the tracks.  I have a pic (attached) from Gerry at the factory but wanted to solicit the wealth of knowledge here.  Anyone have suggestions/advice on length, placement, and car type?  They also recommend stops on the ends of the track but I kind of like open track so I can remove the cars when not in use, or at least on the forward ends of the track (to keep from snagging the sail).  Open to thoughts and suggestions.

Thanks

Today was my lucky day, while grabbing the boom off the boat to replace the end caps and wax it, I found an 8' stick of 1" T track. So now I just need to determine location and which cars to use. Still open to suggestion and advice; particularly experience based.
Thanks

Haven't used, but I have many other pieces of Garhauer hardware on my boat and think very highly of them. Tremendous value too.
