Hey there!
Thank you for the suggestions and please, keep them coming!
I would prefer to hold on to the idea of UK club, since I already contacted two there, but as far as I know since April there have been some changes in their regulations regarding SPL licensing.
Besides that Brexit thing is kinda worrying, at least for me. It seems to me like I might fall on the wrong side of the fence again. Once that happened, otherwise my glider experience would've been recognized in EU now.
I won't scratch UK of course, they have great traditions in gliding. Just sharing my current perspective.
ASK-21 and LS-4 next seems like a perfect combo and this is mostly what I discover throughout my research.
Please, if anybody would like to share more clubs - do so. I will email most of them anyhow.
Thank you once more
