I managed to reduce the latency from 17 to 13, which makes me quite happy. My favorite part of the solution is the third input, which copies the elements from the first one. I think this is faster than using the annoying Wheel again.
But although the Elementification is fast, the assembly of the input takes quite a lot of turns and regrabs.

All in all, I really like this solution, but I have higher hopes for Height. ^^
