if you look at most ambilobes they ave a Y shapped barring pattern in the middle where two bars from the top meet at the middle stripe and become one thicker bar on the bottom bar set below the middle stripe. Sambavas usually have a U bar with no bar below the middle stripe in the middle of their bar sets. It is kinda cool to see an ambilobe with a different patter set than the normal Y. I like it and his colors are very nice for his age. Good luck.
