He states that he is using the Nilex set, which implies (nee guarantees) he is driving the XFG.
To the OP...Be aware that Nilex XFG set does not suit all, which is one of the reasons why you may be struggling. As said above go online and watch some fast guys and ask for their set (do not be offended if turned down and only ask once).
I have helped quite a few new guys at Bl in XFG by watching them, giving advice and adjusting/giving sets, so feel free to search my user name and I will do what I can to help.
