I was the one who was flying the prototype of the UL Giles with an OS. 1.60fx and pitts muffler. mine weighed 10lbs flat RTF. The plane is amazing for both 3D and pattern flying. It flys the pattern like a 35%er and 3D's like a foamie.

I have also flown the showtime a bit. it is great for more sporty flying than the Giles. i think it is to heavy for its size where yes the Giles is a pound heavier it also is bigger - 76" . The showtime is a decent overall flying plane, but if you want something that flys like a bigger plane and is more practical for pattern and/or 3D manuevers, go with the Giles.
