Greenleaf's 70/30 blend which is 70% soy, in my opinion, has an awesome scent throw compared to the 70 para/30 soy that I have tested and I have tested J223/soy, 4627/soy, 4786???/soy (can't remember if that is the correct number, it has been so long), JS 50/50, 6006. I am really pleased with the scent throw so far and so are my co-workers. I do have to let them cure longer though and I can tell a big difference in scent throw after curing. Just my opinion though.
