Thanks VERY much to everyone for your practically instantaneous feedback! I am very much encouraged by your suggestions -- it is apparent that I do not have enough crew weight (easy to remedy, with the promise of ice cold refreshments afterwards), and its clear that I'm not cranking down enough on the backstay and shrouds. I did seem to occasionally find that "groove" and point very high, but felt like I needed more drive from my jib. Does anyone routinely go down from a 155% #1 to a #2 -- seemed like the #3 was too small.
Thanks again for all your tips!
Now I know why I have always been happy that I got my J/30 17 years ago. You guys are great!
