Partner wanted for climbing this weekend in Zurich!

I'm looking for a climbing buddy to ideally take on some more challenging routes - my current partners climb at up to 6b ish but I'm now climbing around 7a and would like a partner to push me a little at this level and beyond! As a start I'd like to do some climbing in / around Zurich this weekend, ideally in Gaswerk Schlieren. My German is decent but ideally looking for someone with strong or native English. I'm a confident and attentive belayer and have every imaginable piece of gear.
