I had a similar frog made by Yita off of ebay, as I saw they were making a knockoff Kolstein bow. I really like the feel of it. I swapped frogs with my chinese carbon fiber bow.

I had a Steven Reiley bow with a Viennese Frog for a year or two. I play with a similar grip to Ludwig Streicher. I find that the traditional frog facilitates my technique better. If it works for other people though, more power to them!
