There is nothing to worry about with silverware and brushless, it’s a great match, and size does not matter. I have found silverware to be very safe and dependable. Best to stick with a known good board like E011/B03/H8 blue, I would not use any of the other lesser-known brushed boards. Hey, I took the 90mm frame out again this morning for a sanity check, to see if the new PID controller really is as good as I thought it was yesterday - haha, it’s even better than I thought
Regarding the 1102 with 2" props, I wouldn’t go smaller than 3020 (2-blade) cut to 58mm if I could help it, as I know that works well, but I haven’t tested smaller than that.
