Questions for anyone building the CLC teardrop

I really enjoyed pouring over Friz's build journal for the CLC teardrop. I love the size and shape of it, and that it weighs in at around 500 lbs including trailer. I'm also a big fan of the stitch and glue process. I built a CLC boat years ago and the thing is still rock solid after 18 years of paddling in salt water. I am undecided though as to whether I will build from the CLC kit or build a more traditional tear. Cost wise, estimates for both methods are running about $3K (for me anyway).
For anyone who has built a CLC tear I have a few questions:
Do you think it makes sense to epoxy a piece of glass on the interior doors prior to cutting them out to help minimize spring back?
CLC offers an insulation kit for a whopping $345. Cha-ching! Friz used rigid foam in his which I would like to emulate. Would it make sense to use the cabin pieces as templates to cut foam insulation before stitching everything together?
Mushroom vents - good idea or bad idea? From what I have read some people are experiencing water intrusion on the road during rain storms.
If you did it again, what would you do differently?
FYI, I see on CLC's live shop cam they are building a prototype for a raised platform that the tear will sit on and will include drawers on the back and sides. This will raise the height of the galley approximately 8-12 inches. They are planning on including a stow-able step that can be pulled out.
Thanks!
