The red maeng da for me made my eyes feel strained but I've only tried it once so could have been the batch. I know the green Borneo is really good and have heard the red Borneo is too, I tend to stick to a type when it works well but yeah the green Borneo for me is up there, I'm gonna buy the red Borneo next time, the green kasung is also decent. KUKs Bali gold is good kratom, but not worth the price is all, and to me it's the only kratom they sell that's worth buying. Wouldn't worry about
