Welcome aboard! Your order has lots of really nice options. I totally get the woulda-coulda-shoulda on what will likely be for some of us a once in a lifetime opportunity. Breeze makes lots of high quality options (as do other forum vendors): I have many on my build.

Glad you were able to go to the build school. I booked twice, but both classes were cancelled due to COVID restrictions. I didn't end up attending. I think it would have given me some great insights into the build, not to mention the great perspective you can only get from real-life hands-on. I think it will be a great advantage to you.

Enjoy your pre-build prep. tasks.
