In all seriousness though - go with what MakD has said, try and try and try different paints. You definately can't go on what other people say. Even in our team - we often shoot two different types of severe paint, as some of the lower grade is fine with the majority of our markers (Cockers) but those like myself need higher grade to go through the likes of Angels.
(I say this before this thread turns in to a Sponsorship war!)
Well we went up to Elsham today and tried out some paint (Hurricane), its pretty good paint, i used a borrowed Angel and it was going through it with out many breaks.
