Ramin is no longer being imported into the U.S. as I understand it, due to environmental concerns. Birch makes a good arrow, and is readily available and pretty cheap. I just posted my experiences with some that I bought that may be of interest. I found that by leaving them long and using big feathers, most can be shot as is with minimal work for stumping, small game, etc. Of course, you can work them down into a matched set of tournament arrows, too, if that's your bag.
Good luck,
