From what I've heard, the Adox paper is made by Fotokemika, and thus may be the same as Varycon. I have used that several times over the last 30 years, and still don't know if I love it or hate it. It is capable of giving great results, but also of causing me to attempt to tear out the last of my hair (so little left it's difficult to get a grip on).
Warm tone, easy to tone, liths to a weird pink tone when it doesn't explode in pepper fog, tends to take tone in the highlights as well - even unexposed paper. Long toe, so "maximum black" is often unattainable. The toe stays long with any kind of filtration, so you may get hard highlights with soft shadows. Sometimes it's good, sometimes it sucks - and it all depends on the negative and how you use it.
