Well I tried opening a few closed minds. When Vision came along every one went mad trying a new additive. Just shows we are only happy if it cost a lot.
Slap there are a few who are only interested in promoting Vision so they have no interest in listening or hearing about other
additives or cheaper alternatives.
You have an even smaller few who for some reason want to experiment with additives and when asked don't seem to know why.
Then you have the majority who are happy and getting great results with pure alone so have no interest in finding a magic
potion.
That's it in a nutshell mate it nothing to do with open or closed minds.
