The Lima plastic is not as torque resistant. Touchy on the forehand release. With the right slight hyzer though, it will flip up to flat and ride for days before slightly fading to finish. Put too much power through it with a flat release and it is going to turnover quick into a roller. 

The Curl has an extreme amount of glide and can get reliable distance once you learn the release angle. There can be a learning curve though to control the US driver. Especially in Lima, it is very touchy with a forehand release. With the right angle it will flip up and turn for days. If the release is slightly off with too much torque, it will turn and burn into a roller every time 

The Lone Star Curl is a great-feeling distance driver with a flight pattern that falls somewhere between the Innova Wraith and Latitude 64 Sapphire. It has a little less stability and more glide than the Wraith while still finishing with a more reliable fade than the Sapphire. I didn't think I had a place in my bag for the Curl, but it was so much fun to throw that I ended up culling out my Wraith to make space for it.
