I went out since it is warming up here in Michigan and threw both my 173g peach Escape and my 171g blue Escape.
First off, the plastic is very stiff and a bit slippery like others have said in previous posts. I didn't notice it much before because I was throwing with my gloves on in the snow. However, I felt that I was releasing the disc early until I got a hang of the plastic.
For the flight of the disc, I really wanted the disc to fly like my 11x TB's but I think they are a bit shorter then that. The flight is very similar though with a straight HSS and then a short fade at the end. I feel that I would throw it on holes that i would throw the TB at.
Overall, the colors don't change the stiffness of the plastic. Both feel the same.
