What do you mean 'Techfind'? I assume you just mean Techcopy? Perhaps it's different for you since you'll have the US version I expect. However for me Techcopy doesn't really flash, it just changes from green to a more yellow-green I don't think the colour matters for me.

I will try exhibitions though, does anyone have an easy way to get the other player's to use volley shot? I can't seem to make my defenders go easy on them
