The way i look at it is if you have to ask the question then you have some doubt about doing it. If you have a doubt then if you do run the cheap rod down the barrel and it doesn't shoot like you think it should you will blame yourself and the cheap rod. By waiting you take the doubt away and know you did all you could to do everything right. I am not saying the cheap rod will do any damage just hate when i know i could have messed up something by not waiting. And that folks is why i said "WAIT"
