I don't like kites much but they are very good in this puzzle.
I used a kite, an xy-wing and finished with another kite. Fun puzzle!

I only worked with digit <2>, starting with a kite, then a type 4 UR, two xy-wings on <269> using the same pivot and one transport, and finally coloring.

Very enjoyable puzzle Exclamation
