Hi JP
I use george ( two years now) but did download the wcp trail.
Got to say that as a sole trader george does everything I need, but might be cos I'm used to it. I ran the two for a week and they are very similar.
The wcp is more upto date and may have or get better updates. Of the two, take your pick.
George is great valve but if you like to use the computer wcp may be more friendly
Not much help, eh?
Tony
