Yeah I had a feeling about the RY5. I just ordered 60ml of the RY4 and grabbed a 10ml bottle of the RY5 to try. Now I am thinking I will regret not getting more RY5. Oh well, luckily the RY4 is amazing. I have tried a few different RY4s so far and FSUSA is by far the best one. Would definately like to hear more about the oRYental 4 though...
