hello
Hi I've done my 320 rating at C4U in june/juli and I can do my base training this month! That's 2 months in between for me.
It is a very relaxed team of people and the training I got was very good, especially the sim-sessions. It's not a very big school, which for me made it a nice atmosphere to work.
The best thing would always be to go there and talk to the people. The ticket to Berlin would be little price to pay if you're willing to invest a bigger sum in a TR.
