Hi Paul,
A couple things to add. I see you are in Vancouver as am I and we do end up in the rain at times. On my Hunter and my friends Catalina water will drip into the cockpit where the "connector" attaches to the dodger and eventually down the person's back who is sitting there. I wish it was designed differently to avoid this. I purchased a light summer tarp to prevent this.
For your connector think about the number of windows. I prefer 3. Same for the dodger. You already have a frame so that will influence your decision but again think about the number of windows.
Our current boat has Strataglass which I really like. I am not sure how old it is as I have had the boat for 2 years. I think it is 40 thickness and it formed a curve just fine on the side windows. It does not have covers. I am not sure I would add them. There is a good article in Practical Sailor on pros and cons.
Our previous boat had Lexan windows which also worked well. I replaced them after 10 years with Strataglass. I don't think the dodger was designed to tension the strataglass as it was too wavy. The canvas company agreed and changed it back to Lexan.
There are many experiences with dodger windows. The region we live in makes a difference in how much sun/heat etc compared to other regions. Even the amount of salt in the ocean.
I did way too much research but the best method for choosing the glass was having an experienced person walk me around the marina showing all the different examples on existing boats.
