This time you`ve answered all your own questions ! Good way to keep the thread short.
A while ago I asked what a "comptip" was, not being in the US & having not seen or heard of one before. I assumed it was a performance modification which would do exactly what you`re talking about, turns out to be a "safety" feature for lightning protection. I thought, wow, similar to the 49er that has a carbon/fibreglass upper section to the mast for increased flexibility & gust response. Turns out the responses I got to my question were mostly negative, seems the Hobie guys don`t think it is much good for performance. I think they would have to redesign the mainsail to get any benefit from this modification, squaretop main & flatter cut sail might help, but of course, class rules say no. Pity, I reckon if Hobie made their boats a few kilo`s lighter, modified the mainsail to suit the new mast & promoted their spinnaker kit more, they`d be able to upgrade their class to stay with the pack. I found a pic of a rig I think they were testing out for the youth boat selections on their web-site, see attachment. This modification looks suspiciously like they designed the rig to fit into the F16 class, which could only be a good idea in the long term.
