Ramin,to me, seems to be straighter. I think it is just as tough as hickory. The ramrod I use is made of Ramin wood. Granted,I don't shoot a lot (maybe use 1/2 lb powder a week),but I use my rifles ramrod all the time.I do not use or take any other rod with me when I go shooting.I am sure you would be happy with it.
PS: I soak my ramrods in coal oil (kerosene) for at least 3 months.
