I had a webshop using WPML and WCML, but your currency switcher droped extremely the performance of the website. So for a new webshop I'd like to use a lightweight currency switcher (need only USD and EUR). Some comforts of WCML I could adjust or program on my own (strings, e-mail, checkout-points). Does your team already have tested this combination of plugins?
I would like to avoid to create a lot of bload for many users only due a currency switcher. I would use the paid version of Curcy, not the free one.
