Can I go from Avistar to omp to edge .40?

Or should I go for a Ultrastick 40 for a 2nd plane and omp as 3rd.

Also I built a zagi but I want to know if it is possible to get an arf version of the omp edge .40?

if so what is a good visible paint scheme i was thinkin bout solid color in top with a different base color on the bottom with a different color stripe. What yall think.

Thanks in advance
