I haven't noticed any issues with a Canadian exit point although I guess that'd be on the wrong side of the Atlantic for ya.

I've always gone with Netherlands..... Based on nothing except that UK sucks ass and blocks or age checks anything good, and no such obstruction has ever been seen when I've used Netherlands proxy.

Could it be CH?

Just like Switzerland, Austria is also a good choice - any blocking is normally DNS based and not network based here.

There shouldn't be any kind of blocking in Hungary.

I always go to the middle east. They have bigger fish to fry.

As a hungarian, i dont use vpn or anything like that but never had problem with torrenting. So maybe try hungarian
