Hi there. I think you will find it pretty good here. We have a good relationship with atco's here and in the past we have been invited to various towers and also to Farnborough too. I know for a fact there are loads of atco's who are ppl's and they contribute from both sides of the fence on here. I think you will have to go far to find someone against them if indeed that is what you are looking for.
I think the feedback will be very one-sided.
