If you've already found links to the vinhtran tactics and tweaks that I and others did, download and test them. Many people were very successful with the original tactic, others had with my tweak, others with tweak from StefanoPT, others from Galician ... I do not think it has one better than the other. Just you test and see which goes best with your team. I recommend testing initially with the original vinhtran tactic.
Which one are you using now, as I can see that you uploaded your own 433 yesterday?
