I'm not sure if that was the answer you were looking for, but just keep checking this thread and i'm sure someone will tell you what you could specifically use to better your speed. Keep checking this thread or make a new one with a title that is more specific to make people look at it, when i saw the title i thought it was talking about speed as in the drug, like adderall or ritalin lol, but thats just me.
"Help!!!" is a possible title, it will get peoples attention, make it sound needed, since it is for you.
