This depends on the stringer and your comfort level with String Zing. After using String Zing two or three times, most stringers start to see the benefits which include faster racquet stringing, no errors in cross string weaving and better ergonomics while stringing. Plus, it is way more fun to do the cross strings.
YES, String Zing works exactly the same for either a one or two-piece string job.
YES, String Zing works well with any type of string from gut to synthetic to stiff polyester.
String Zing is designed to work on all tennis racquets with head sizes up to 110 square inches. It is also designed to work with a variety of string spacing patterns.
It will work with some oversized frames but not all of them.

Great question. It is such a simple concept, yet no one came up with this product in the past. It's likely that many folks have tried similar approaches but not been able to create a design that worked effectively. The String Zing took months of prototyping to develop a working design and many more months to hone the design into a viable product.
Once you are comfortable that the String Zing device allows you to simply pull the cross strings quickly through the main, you will start to look forward to doing the cross strings and it will be the fun part of the racquet.
