I'm on SF Bay and have a 110 (well, I suspect it might be closer to a 115, but close enough!). I usually have my car right at the front end of the track. Close hauled I might bring it back slightly when the wind kicks up. The real problem is when I roll up the jib a bit to reduce sail--no ability to move the car forward. Probably why I usually sail with a full jib--the performance reduction is more than I can accept when I reef the jib. I had thought about trying to add some track too, but finally decided that the few times I would really need it weren't worth the trouble.
